Rhodium Nanoparticle-Supported Graphitic Carbon-Encapsulated Nickel Metal Core Electrocatalyst via Pulsed Laser Ablation for Hydrogen Evolution Reaction.

ABSTRACT: The hydrogen evolution reaction (HER) in acidic media exhibits high reaction rates but is often hindered by stability challenges under corrosive conditions. In this study, we introduce a novel approach to synthesizing nickel nanoparticles encapsulated in nitrogen-doped carbon layers decorated with noble metals (Ir and Rh), with the aim of improving catalytic activity, durability, and conductivity for HER applications. Using a two-step pulsed laser ablation and irradiation process, this environmentally friendly synthesis facilitates the rapid production of Rh- and Ir-decorated Ni@GC composites with robust metal-support interactions. The resulting catalysts exhibit outstanding HER performance in 0.5 M H₂SO₄ acidic electrolyte, achieving a current density of 46 mV at 10
