Abstract:Engineering the lattice oxygen reactivity and activation
of gaseous
O2 is vital for boosting methane combustion over Co3O4. Herein, zinc was inserted into the Co3O4 matrix, driven by its slightly larger cationic radius
and lower electronegativity than those of cobalt. The suitable doping
of zinc offered the optimum occupation of Zn2+ at the tetrahedral
sites, granting more active Co3+ sites. The formation of
Co–Zn–O solid solution delivered the lattice disorder
and endowed cobalt with richer electrons, which i… 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.
