Abstract:Controlled assembly in aqueous solution was used to synthesize the well-organized Pt/CS/ PW 12 -GNs composite. By the aid of linear cationic polysaccharide chitosan, 2-D distribution worm-like Pt nanoparticles with their length and width of 15-20 and 3-4 nm, respectively, were formed on the surface of CS/PW 12 -GNs using HCOOH as a reducing agent at room temperature. The introduction of CS leads to well dispersion of worm-like Pt nanoparticles, the electroactivity of H 3 PW 12 O 40 (PW 12 ) alleviates CO poiso… 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.
