Summary: Recognizing and understanding active sites for novel photocatalyst systems remains a challenge, and it is important to regulate the local geometry and electronic structure around these sites. Doping engineering and defect engineering are effective strategies for modulating the configuration and electronic structure of active sites. Through a synergistic effect of dopant and induced vacancy sites, the reconstructed active sites exhibit asymmetric geometry. This systematic overview focuses on doping engineering and defect engineering strategies for enhancing photocatalytic performance. The asymmetric geometry of the reconstructed active sites leads to unique electronic properties, whose mechanism is thoroughly revealed. Various photocatalyst systems using dopant synergizing induced anion vacancy for different applications are outlined, including energy conversion and pollutant removal. Additionally, the fabrication of doped, defective photocatalysts and photocatalyst systems with dopant-induced vacancy is described.
