主　　题：interface engineering CoS/CeO_(2) electrode-position electrocatalyst oxygen evolution reaction 

摘      要：To realize renewable energy conversion,it is important to develop low-cost and high-efficiency electrocatalyst for oxygen evolution reaction.In this communication,a novel bijunction CoS/CeO_(2) electrocatalyst grown on carbon cloth is prepared by the interface engineering.The interface engineering of CoS and CeO_(2) facilitates a rapid charge transfer from CeO_(2) to CoS.Such an electrocatalyst exhibits outstanding electrocatalytic activity with a low overpotential of 311 mV at 10 mA·cm−2 and low Tafel slope of 76.2 mV·dec−1,and is superior to that of CoS(372 mV)and CeO_(2)(530 mV)counterparts.And it has long-term durability under alkaline media.
