Facile Electrodeposition of WS2/Ni3S2 Heterostructure on Nickel Mesh as Binder-Free Electrocatalyst for Enhanced Hydrogen Evolution Reaction
: Electrocatalytic hydrogen evolution reaction (HER) underpins the scalable synthesis of renewable green hydrogen, yet conventional catalytic systems are constrained by overreliance on scarce noble metals, sluggish mass transport kinetics, and inefficient intermediate modulation. In this work, an efficient HER electroc...
