Nonprecious metal oxygen reduction reaction catalysts have been prepared via a simple chemisorption-based methodology. First, an aminosilane was chemically attached to a carbon surface, followed by coordination of iron and subsequent high temperature pyrolysis. Catalysts were prepared from a series of mono, di, and triaminosilanes. Physical and electrochemical properties of these catalysts were studied using inductively coupled plasma optical emission spectroscopy, X-ray photoelectron spectroscopy, and rotating ring-disk electrode cells. Maximum catalytic activity was achieved for samples prepared from the triaminosilane combined with a more disordered carbon black.
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.
