Platinum and copper nanosheets alloys (Pt 1-x Cu x nanosheets), prepared by the seed-mediated growth method, are deposited on mesoporous titanium dioxide (TiO 2 ) doped with carbon black by ultrasonic dispersion. The Pt 5 Cu nanosheet/carbon-TiO 2 (Pt 5 Cu NS/C-TiO 2 ) used for proton exchange membrane fuel cell (PEMFC) catalyst shows higher electrochemical surface area and exhibits better fuel cell performance than that of the commercial Pt/C catalyst. The Pt 5 Cu NS/C-TiO 2 also shows better stability than that of the commercial Pt/C when it is employed as the cathode catalyst in a single-cell fuel cell.
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.
