Research Interest

  • We are working on designing and synthesizing new nanoscale materials and structures with an emphasis on rational control of morphology, size, structure, composition and doping of metal carbides, nitrides, sulphides, phosphides, oxides etc on multiple scales for Energy and Environmental Applications.

    Nanostructured composite materials for photoelectrochemical applications; Rechargeable Metal-Air Batteries and hybrid energy storage devices; Active catalysts for Oxygen Reduction Reaction for Nonaqueous Air Batteries; Development of low-cost, stable and efficient electrocatalyst for development of PEMFC; MOF based polymer electrolyte; Nano-materials mediated catalysis for organic transformations; Engineered nanomaterials for Air/Water purification

Research Highlights

  • The oxygen reduction reaction (ORR) is critically important in energy converting systems, and the advancement of a  catalyst that accelerates the process is vital. Here, an ORR electrocatalyst was developed by the stoichiometric addition of Co(II)  ions to a model composite (FePH) and termed as γ-CoFePH. The developed electrocatalyst shows a significant enhancement in  ORR activity with improved Eonset and E1/2 (3 mA cm2) values, where E1/2 is 0.29 V as compared to 0.60 V for FePH, drifting toward Pt/C and exhibits a limiting current density of 6.3 mA cmwhich exceeds the commercially available Pt/C. The γ- CoFePH also displays superior resistance toward methanol poisoning and stability of over 40 000 s retaining 83.6% of the current 11 density under alkaline medium.
  • Transition metal sulfides have been established as an excellent hydrogen evolution reaction catalyst but their oxygen evolution reaction behaviour is still less explored and needs further investigations. Oxygen evolution reaction has a huge potential for fuel cell and air battery applications. Ashish et al. have synthesized MoS2 nanolayers on N-doped carbon wrapped cobalt submicrospheres shows excellent OER catalytic activity.

  • Hydrogen is one of the cleanest forms of energy which can solve several issues, including environmental pollution and depletion of fossils fuels. Hydrogen evolution reaction (HER), being a carbon-neutral process can reduce the carbon footprint in the earth’s atmosphere. Molybdenum based solids are among the most popular electrocatalysts, which have been explored extensively for HER processes as an alternative to Platinum. Herein, we report a nanostructured electrocatalyst (CuMoCat) consist of molybdenum carbide, molybdenum nitride, and elemental copper, forming a heterojunction within the composite. Copper doping in molybdenum carbide/nitride composite not only facilitates the lowering of the overpotential but also improves the catalyst to perform at high current density. CuMoCat exhibits an overpotential of 82 mV for attaining a current density of 10 mA cm-2 with a Tafel slope value of 33 mV/dec and shows excellent stability of 3000 cycles in acidic media. The theoretical study reveals that Cu doping brings a change in the electronic properties of the catalyst, which improves the overall adsorption and desorption of hydrogen on the catalyst surface during the hydrogen evolution reaction. The Free Energy diagram for ‘Mo’ and ‘N’ hydrogen adsorptions sites of CuMoCat displays, a shift of free energy making these more favourable for HER with respect to Mo/N sites of the un-doped catalyst.
