It is a huge challenge to design and develope a highly active and stable non-noble metal electrocatalyst for hydrogen evolution reaction (HER) in alkaline solution. Increasing the active sites and improving conductivity of catalysts are the effective ways to enhance the catalytic performance. Here, nanoparticle-stacked porous NiCoO2@C microflakes arrays grown on Ni foam (NiCoO2@C-NF) was synthesized...
We report a novel and simple approach to synthesis highly efficient and stable electrochemical catalyst of Ni-(MoS2/GO) composite coatings by electrodeposition from aqueous solution with the nickel sulphamate precursor. Depositing under supergravity fields has been applied to scatter more MoS2/GO hybrids in the coatings and decrease the size of nickel particles as far as possible and increase large...
