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.
