MajorAreas of Research 

  • Development of Graphene Oxide Supported Mixed Oxide Photocatalysts for Photocatalytic Water Splitting to Produce H2, Photocatalytic and Sonophotocatalytic Degradation of Organic Pollutants. 
  • Synthesize of Graphene Supported Electrocatalysts for Oxygen Reduction Reaction (ORR) and Direct Methanol Oxidation Fuel Cell (DMFC) Applications. 
  • Designing of Graphene Oxide Based Hybrid Nanocomposites as Photoactive Layer or Buffer Layers for Polymer Solar Cells.

Recent Accomplishments 

  • 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.


Figure: Proposed mechanism for photocatalytic Cr(VI) reduction and H2 production using carbonaceous polymer coated TiO2 photocatalyst.

  • 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.
