Plasma as a promising solution to catalyst synthesis and modification has received great attention in the field of electrochemical water splitting. However, comprehensive overview detailing how plasma treatments catalysts enhance oxygen evolution reaction (OER) performance is currently lacking. Here, we review advances challenges cold for preparation modification. We discuss underlying mechanisms responsible enhanced OER on plasma-treated catalysts, where surface area, active sites, vacancy type/content, heteroatom doping, etching, functionalization could be mediated. This aims provide valuable insights into role advancing electrocatalysis sustainable energy applications.

Nanocomposite electrode materials based on Pt nanoparticles (Pt NPs) deposited various carbonaceous (Carbon Black-Vulcan XC72, graphene, and graphite) were fabricated evaluated for ethanol electrooxidation reaction (EOR) in acidic media. The promotional effects of calcination incorporation metal oxides (TiO2, SnO2, ZnO, Fe2NiO4, Fe2O3, CuFe2O4, ZnFe2O4, 5% Ru alumina) into Vulcan XC-72 the performance NPs toward EOR systematically evaluated. (∼20 wt %) synthesized via a facile NaBH4 reduction method at ambient temperature, yielding spherical with minimal agglomeration. Physicochemical characterization (XRD, TEM, SEM) confirmed uniform dispersion reduced particle size calcined Fe2O3-C supports. Electrochemical analysis (CV, CA, LSV, EIS) revealed that Pt/5% exhibited superior activity, low onset potential (0.2 V vs Ag/AgCl), high current density (0.52 mA/cm2), enhanced stability (retaining >34% activity after 3000 s). Dual (pre/post-Pt deposition) stabilized ultrasmall (3.09 nm) Fe2O3-C, achieving 2.3 times higher mass than Pt/C. improved is attributed to synergistic electronic effects, optimized Pt-support interactions, Fe2O3-mediated C-C bond cleavage. This work highlights efficacy dual thermal annealing (pre- post-Pt stabilizing advancing DEFC catalyst design.
