Initiating highly efficient (Bi,Ce)₂(O,S)_3−<i>x</i>oxysulfide catalysts with rich oxygen vacancies for hydrogen evolution<i>via</i>adjusting valence band configuration

Abstract

Converting Bi 2 S 3 into an efficient PHER catalyst by defect engineering to form solid solutions with the incorporation of Ce and O into Bi 2 S 3 for bimetal–chalcogen (Bi,Ce) 2 (O,S) 3− x catalysts.
