Two nickel/nitrogenated graphene hybrid electrodes (Ni-NrGONH3 and Ni-NrGOAPTES ) were synthesized, their catalytic activity with respect to the hydrogen evolution reaction (HER) in alkaline media was analyzed. Incorporation of nitrogen carbon structure oxide (GO) or reduced GO (rGO) flakes aqueous solutions carried out based on two different configurations. NrGONH3 particles obtained by a hydrothermal method using ammonium hydroxide as precursor, NGOAPTES silanization (APTES...
This study explores the impact of incorporating tungsten carbides into a Watts bath on fabrication Ni/WC and Ni/W2C composites, comparing them with conventional Ni electrodeposited electrodes. Results indicate that adding to nickel forms rougher more porous structures in deposited composites. Composite electrodes exhibit significantly enhanced current density for hydrogen evolution alkaline media compared Differential Electrochemistry Mass Spectrometry (DEMS) elucidates mechanism, providing...
Hybrid Ni–MoS2 electrocatalysts are one of the most promising materials for generation hydrogen in an alkaline medium. This paper presents a simple and economical method rational synthesis nanocomposites, maximizing contact area reducing resistance between MoS2 nickel surface. In this way, it is possible to maximize synergistic effect both materials, obtaining hybrid nanomaterial with high electroactivity toward hydrogen. A conventional catalyst (NWts) was compared obtained by dispersing...
