Benefited from the optimized activity of active sites, adsorption energy and the proposed electron transfer property, the CoFe2O4 nanosheet with oxygen vacancies exhibited significantly enhanced water splitting catalytic performance.
Amorphous cobalt-doped MoO x (CMO) nanospheres with a unique core–shell structure have been successfully fabricated via a simple hydrothermal reaction. The CMO exhibited enhanced electrocatalytic activity for the oxygen evolution reaction.
