Under the background of increasing energy crisis and global warming, semiconductor‐based pho‐ tocatalysis has received tremendous attention due to its potential application in green energy pro‐ duction, CO 2 reduction and pollutant degradation. The photocatalytic activity of semiconductors, however, remains low due to issues like fast recombination of photo‐generated electron‐hole pairs, limited electron mobility, restricted optical absorption or insufficient active sites. Designing appro‐ priate heterojunctions is proved to be a promising method to address most of these issues and thus to improve the photocatalytic performance. In this review, the working mechanism of various het‐ erojunctions is presented systematically. The most recent advances of strategies in designing and preparing efficient heterojunction photocatalysts are further summarized and some perspectives on the future directions in this field are provided.
