Abstract

Abstract:

Recently, a new opinion was put forward on general design standards for S-scheme heterojunction photocatalyst. Four types of S-scheme heterojunctions were analyzed. Specifically, the critical understanding on the curved Fermi level at the interface of S-scheme heterojunction is helpful to strengthen and promote the basic theory of photocatalysis.

Key words: S-scheme heterojunction, p-type semiconductor, n-type semiconductor, Curved Fermi level
