Abstract:La 0.65 Ce 0.25 Pr 0.02 Nd 0.08 Ni 3.85 Mn 0.39 Co 0.73 Al 0.31 AB 5 -type alloy was modified via the method of a simple chemical oxidative polymerization of pyrrole (Py) directly occurring on the surface of alloy particles. Field emission scanning electron microscopy and Fourier transform infrared spectroscopy revealed spongy polypyrrole (PPy) films uniformly and continuously deposited on the surface of the alloy particles. The PPy films possessed superior electrochemical redox reversibility, thus facilitatin… 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.
