Abstract:In this work, we have described a polyoxometalate (POM)-based inexpensive and easily synthesizable compound [Co(H 2 O) 6 ] 2 [{K(H 2 O)} 2 V 10 O 28 ]•2H 2 O (1), which exhibits electrocatalytic hydrogen evolution in its aqueous solution without its decomposition (or electrodeposition), acting as a rare homogeneous electrocatalyst. Even though the compound [Co(H 2 O) 6 ] 2 [{K(H 2 O)} 2 V 10 O 28 ]•2H 2 O (1) (soluble in water) shows electrocatalytic hydrogen evolution reaction (HER) activity because of the Co… 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.
