Abstract:Five types of niobium(V)
oxides (Nb
2
O
5
) were
synthesized by hydrothermal and heat treatment processes, and their
structural properties and catalytic activities for the hydrogen absorption/desorption
reactions of magnesium were characterized. The synthesized Nb oxides
were dispersed on magnesium hydride (MgH
2
), a typical hydrogen
storage material, using the ball-milling method. All the synthesized
Nb oxides improved the reaction kinetics… 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.
