Abstract

In this work, a Se–O bond is introduced by a simple oxidation method to realize the structural transformation from Cu_2−xSe to Cu₂O(SeO₃) for enhanced electrocatalytic hydrogen evolution reaction (HER). The experiment and calculation results showed that Cu₂O(SeO₃) facilitated charge transfer and possessed a small Image ID:d3cc04054b-t1.gif barrier during the HER.
