Abstract:Platinum nanoparticles (PtNPs) are prepared from an aqueous
H2PtCl6 solution using the sodium citrate method
and supported on single-heteroatom-doped (S, N, and P) and dual-heteroatom-doped
(N–S and N–P) graphene. The influence of the support
of the electrocatalytic activity of PtNPs toward the oxygen reduction
reaction (ORR) is investigated to assess their suitability as cathode
materials for proton exchange membrane fuel cells (PEMFCs). Physical
characterization of the catalysts proves that the PtNPs are eve… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
