description Because of the interactive combination synergy effect, hetero interface engineering is used way for advancing electrocatalytic activity and durability. In this study, we demonstrate that a CeO /Bi WO heterostructure is synthesized by a hydrothermal method. Electrochemical measurement results indicate that CeO /Bi WO displays not only more OER catalytic active sites with an overpotential of 390 mV and a Tafel slope of 117 mV dec but also durability for 10 h (97.57%). Such outstanding characteristics are primarily attributed to (1) the considerable activities by CeO nanoparticles uniformly distributed on Bi WO nanosheets and (2) the plentiful Bi-O-Ce and W-O-Ce species playing the role of strong couples between CeO nanoparticles and Bi WO nanosheets and oxygen vacancy existence in CeO nanoparticles, which can improve the electrochemical active surface area (ECSA) and activity, and enhance the conductivity for OERs. This CeO /Bi WO consists of the heterojunction engineering that can open a modern method of thinking for high effective OER electrocatalysts.
