摘要
Transition metal chalcogenides has been reported to be an efficient catalyst toward oxygen evolution reaction (OER) catalysts. Developing a reliable heterogeneous structure strategy to modulate the electronic structure of electrocatalyst is a key challenge. Herein, we investigate an efficient and stable Ni3Se2/Ni3S2/NF catalyst with heterogeneous structure toward OER. The catalyst exhibits excellent OER performance with a low overpotential of 251 and 312 mV at 50 and 100 mA cm−2, respectively. Experiment result shows that the interface of Ni3Se2 /Ni3S2/NF heterostructure triggers abundant catalytically active sites, while regulates the electronic structure of Ni central active site resulting in fast charge-transfer capacity and superior electrochemical performance. This work provides an effective interface regulation strategy for developing applications of other advanced heterostructures.
