Water splitting reactions by photochemical and electrochemical means is an important area of research related to renewable energy. Recently, we studied nanocomposites of carboxyl-functionalised MoS2 nanotubes with PDDA-modified single-walled carbon nanotubes and Borocarbonitride nanotubes, solid solutions of MoSxSe(2-x)/MoSexTe(2-x), Phosphorene MoS2 and Phosphorene-MoSe2, nanocomposites of PDDA functionalised RGO or BCN with MoS2 and MoSe2. We have also investigated the role of interlayer separation of the covalently cross-linked 2D nanosheets and its effect on hydrogen evolution. We have investigated various classes of 2D materials such as graphene, metal phosphochalcogenides for water splitting reactions and pnictogens for functionalization. We have also studied variations in electronic and optical properties of Cadmium phosphosulfides and their superior photo(electro)chemical HER activity. We also investigated the selective fabrication of β-phase of nickel sulfide (NiS) and vanadium oxide (VOx) thin films, V2O3 thin films via Atomic layer deposition technique with their detail characterisation and ALD parameters dependent study.
Nanocomposite of MoS2/single-walled carbon nanotubes (SWCNT) and MoS2/ borocarbonitride (BC6N) composites which exhibit enhanced electrocatalytic H2 evolution performance with a low onset potential (-113 mV vs RHE) and a small Tafel slope (59 mV dec−1). The combination of MoS2 nanoparticles with SWCNT or BCN appears to be a valuable finding with applications in catalysis reactions.
