Abstract
Solar‐driven photocatalysis has been developing as a sustainable process and it holds appreciable promise to address the pollutants and risks posed by biohazards. The unique geometrical and electric features of 2D semiconductors have nurtured a variety of advanced photocatalytic bactericides where oxidative oxygen species are generated as the main disinfection reagents. Herein, the state‐of‐the‐art progress of solar‐driven photocatalytic disinfection based on 2D semiconductors with an emphasis on the generation and effects of various reactive oxygen species is summarized. Moreover, the immobility of the photocatalyst for practical applications is discussed. Finally, perspectives and challenges are presented to guide future research on photocatalytic disinfection.
