Abstract:In this work, honeycomb-like Yb-doped V 2 O 5 • nH 2 O binder-free thin film electrodes are synthesized via a simple and convenient sol-gel method. Benefiting from the synergy of V 2 O 5 • nH 2 O and rare-earth metal ion Yb 3 + , thin-layer honeycomb-like morphology formed upon the introduction of Yb 3 + into the V 2 O 5 • nH 2 O, which markedly promotes the electrochemical performance of the V 2 O 5 • H 2 O thin-film electrode. After the condition optimization, 8 % YbÀ V 2 O 5 • H 2 O exhibits superior electr… 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.
