Major Areas of Research 

Materials Synthesis

Synthesis of various nano-materials (Pt, Ru, Ag, and Au along with solid support) including semiconductor photocatalysts for Energy conversion (solar and fuel cells) and Environmental remediation

Synthesis of different semiconductor photocatalysts such as TiO2, Bi2O3 nano-particles, nano-rods, tubes, sheets, and flower-like materials by different methods including ultrasonication, hydrothermal, pH swing and sol-gel methods with and without surfactants. The prepared nano-materials is being used in light emitting diodes (LED), solar cell (organic polymer based hetero-junction solar cells), fuel cell (direct methanol oxidation fuel cell) in addition to Environmental remediation.

Semiconductor Photocatalysts

Current  research involves preparation of different semiconductor TiO2 and other semiconductors such as ZrO2, Bi2O3, different metal-doped TiO2, Bimetal incorporated TiO2 and etc, photocatalysts by different methods including pH swings method (novel method) & aerosol method, sol-gel, ultrasonication, hydrothermal and their applications for the degradation of organic and inorganic pollutants both in gas phase and liquid phase reactions, especially NOx, textile dyes and also polycyclic aromatic hydrocarbons. Further work is still going on to establishing these methods to field studies. Fabrication of different photocatalytic-reactors for field studies is still in progress. Recently working on the incorporation of photocatalysts in different zeolite materials and studying their reactivity for the degradation of organic and inorganic pollutants.

 

Metal-Organic Frameworks (MOFs) for Energy Conversion and Environmental Remediation

Our research interests are focusing on the development of new metal-organic frameworks (MOFs) and organic/inorganic hybrid materials for energy conversion and environmental remediation applications. In particular, our main aim is to improve the stability of organic/inorganic hybrid materials and the poor charge carrier separation of MOFs towards the photocatalytic applications. Recently, our research group has developed a new photopolymerization strategy for the preparation of TiO2 – catechol carbonaceous polymeric material. The prepared TiO2 – catechol carbonaceous polymeric materials showed excellent photocatalytic activity towards H2 production under sunlight irradiation and photocatalytic chromium (VI) reduction (Journal of Materials Chemistry A, 2017). Furthermore, we have proposed a new mechanism for charge transfer process between rGO and MOFs by strong π−π interactions for visible light driven photocatalytic H2 production (ACS Applied Energy Materials, 2018). On the other hand, we have improved the charge carrier separation efficiency of Ti-MOF by incorporating Cu2O metal oxide as co-catalysts. It was very interesting to note that the encapsulation of Cu2O co-catalyst on NH2-MIL-125 (Ti) MOF induced the reduction of Ti4+ to Ti3+ sites. The newly formed Ti3+ sites act as a junction of electron extraction level and thereby enhancing the photocatalytic H2 production activity by 28 folds than pristine NH2-MIL-125 (Ti) MOF (Catalysis Science & Technology, 2018).

 

Metal-Organic Frameworks (MOFs) for Chemosensors Applications

Our group is actively working on metal-organic frameworks (MOFs) based chemosensors for selective and precise detection of nitroaromatic compounds such as 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), 1,3-dinitrobenzene (DNB) and 2,4-dinitrotoluene (DNT) which are main ingredients in explosives. In recent, we have developed Fe-based MOF for selective detection of nitroaromatic compounds with the detection limit of 11.5 ppm for nitrobenzene (Microchim Acta, 2017)

 

Bulk Heterojunction Polymer Solar Cell

Organic photovoltaics (OPV) is the emerging renewable, lightweight, large area and low-cost solar cell technology. Recently, the Power Conversion Efficiency (PCE) of state-of-art in polymer solar cells (PSCs) has exceeded 13%. Current efforts in OPV are focused towards developing high efficiency and stable devices with both conventional and inverted solar cell configurations based on donor: acceptor bulk heterojunction concept using the soluble polymers/small molecules  (electron donors) and modified fullerenes (electron acceptor) in combination with suitable interface layers.

We recently developed the new class of metallopolymers such as pyridyl benzimidazole-based Ru complex decorated polyaniline assembly (PANI-Ru) - covalently grafted onto reduced graphene oxide sheets (rGO) via covalent functionalization approach. The hybrid metallopolymer assembly was successfully demonstrated as an electron donor in bulk heterojunction polymer solar cells (PSCs) with 6.7% efficiency. A PSC device fabricated with rGO/PANI-Ru showed an utmost ~6 fold and 2 fold enhancement in open circuit potential (Voc) and short circuit current density (Jsc) with respect to the standard device made with PANI-Ru (i.e., without rGO) under the illumination of AM 1.5G. This work was published recently in Scientific Report, 2017 (DOI: 10.1038/srep43133). Now we are developing various metallopolymers as a light harvesting donor material for PSC.

 

Developing  Electrochemical Sensor Platform for Biomolecules

In our lab we mainly focus on electrochemical sensing of various biomolecules which are potential biomarkers in our body namely dopamine, nitric oxide, bile acids, proteins, etc. We extensively work on designing and synthesizing biorecognition probes using various polymer, graphene oxide materials supported metal, metal oxide nanocomposites via several techniques such as hydrothermal, sonochemical, electrochemical etc. to modify the electrode surface for efficient sensing of the target biomolecule. We aim at developing electrochemical sensors for biomolecules with high accuracy, anti-fouling property, selectivity and sensitivity with low detection limit. Very recently, our group reported electrochemically reduced graphene oxide  (erGO) supported α-Fe2O3 based electrochemical sensor for the detection of biomolecule, dopamine very effectively with lowest detection limit of  24 nM and also shown high selectivity in the presence of other natural interferents in the journal Biosensor and Bioelectronics (2018).

Direct Methanol Fuel Cells

We focus primarily on developing new energy materials as efficient electro-catalysts for direct methanol oxidation fuel cells. Various methodologies are adopted to design hybrid nanomaterials for the oxidation reaction. The reduced graphene oxide supported metal, non-noble metals and metal oxides nanocomposites show better catalytic activity and a greater tolerance towards the poisoning species. Recently, our group reported Tailoring multi-metallic nanotubes by copper nanowires with platinum and gold via galvanic replacement route for the efficient methanol oxidation reaction in the journal Electrochimica Acta (2018).

 

Super-Capacitors

Our group current research focus is also on understanding and developing of carbon nanomaterials especially graphene and carbon nanotube-based flexible supercapacitors to enhance the energy and power densities of energy storage devices. Recent work by our group has demonstrated laser irradiated graphene oxide nanosheets as electrode material for supercapacitor provide improved charge storage capacity and energy density compared with other nanoparticles. In addition, we have concentrated on incorporating spinal mixed transition metal oxide (MCo2O4; M=Zn, Cu, Ni, and Mn) with carbon nanomaterials electrode materials provides improved charge transport and storage [2]. These devices exhibit high capacitance (1496 F/g at 1A/g), good capacitance retention during charging/discharging process. We recently extended this work to design flexible and wearable electrode materials with high energy density for supercapacitor application and use it in replacement of batteries.

Thin Film Coating Technique

We have been successfully carrying out coating of TiO2 and other photocatalysts on solid support like membranes (organic) and glass surfaces by using portland cement and other binders to overcome the problems of separation and leaching of photocatalyst during the slurry method.  Research is still going on to fabricate filed model reactor using solar energy as the light source.

Ultrasonic Irradiation

Our research studies including synthesize of nano-materials using ultrasonic effect, recently TiO2 prepared by ultrasonication with high surface area has been published in Ultrasonics Sonochemistry Journal. Further work is still going using the ultrasonication for preparation of various nano-materials (rods and tubes) and also applying ultrasonication for the complete degradation of organic pollutants present in soil such as Methyl tert-butyl ether, poly chloroethylenes, polycyclic   aromatic hydrocarbons and poly–chlorobiphenyls.  Degradation of these pollutants by advanced oxidation technology i.e. ultrasonic irradiation and also combination with ozonation, Fenton process, etc.

  • We have designed reduced graphene oxide (rGO) supported Cu2O-TiO2 photocatalyts for photocatalytic water splitting to produce H2. The interfacial carrier separation and transportation properties of rGO sheet remarkably enhanced the H2 production rate. Here a maximum H2 production of ~1,10,968 µmol/h/g of Cu2O-TiO2-rGO is achieved. This is the highest H2 production rate obtained in graphene based photocatalysts.

Figure: (a) XRD pattern of different photocatalysts, (b) TEM image of Cu2O-TiO2-rGO, (c) Photocatalytic water splitting mechanism using Cu2O-TiO2-rGO photocatalyst and (d) Photocatalytic H2 production rate using different photocatalysts.

  • Recently, our group has developed a new catalyst (CuO-TiO2-rGO) that works very efficiently under DIFFUSED sunlight. Most of the catalysts which we have prepared and commercially available catalysts can work either in UV light irradiation. The catalysts which we prepared in our lab work efficiently under DIFFUSED sunlight especially certain experimental condition. A maximum synergy of ~10 fold was achieved for the first time using DIFFUSED sunlight as a source of irradiation. This is a breakthrough research work of our group and it will open a new area of research in the near future of using diffused light as a potential source for the degradation of toxic pollutants. In that case, powerful UV light and direct sunlight exposure can be avoided.

  •  Very recently, our research group has developed carbonaceous polymer coated TiO2 photocatalyst using simple photopolymerization process.  Thus, the resultant photocatalyst showed excellent photocatalytic activity towards H2 production under sunlight irradiation and photocatalytic chromium (VI) reduction.

  • N doped graphene quantum dots (N-GQDs) decorated MoS2-Graphene nanohybrid has been developed by our research group and employed as an efficient electrocatalyst for oxygen reduction reaction (ORR) in alkaline medium. The resultant N-GQDs/MoS2-graphene nanohybrid not only showed better ORR performance but also exhibited excellent methanol tolerance ability.

  •  A new class of hybrid light harvester assembly has been covalently grafted on reduced graphene oxide (rGO) sheet and used as an electron donor in bulk heterojunction polymer solar cells. This rGO based hybrid nanocomposites significantly enhanced the open circuit potential (Voc) and short circuit current density of the polymer solar cell device.
