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.

Universal access to clean water has been a global ambition over the years. Photocatalytic water disinfection through advanced oxidation processes has been regarded as one of the promising methods for breaking down microbials. The forefront of this research focuses on the application of metal‐free photocatalysts for disinfection to prevent secondary pollution. Graphitic carbon nitride (g‐C3N4) has achieved instant attention as a metal‐free and visible‐light‐responsive photocatalyst for various energy and environmental applications. However, the photocatalytic efficiency of g‐C3N4 is still affected by its rapid charge recombination and sluggish electron‐transfer kinetics. In this contribution, two‐dimensionally protonated g‐C3N4 was employed as metal‐free photocatalyst for water treatment and demonstrated 100 % of Escherichia coli within 4 h under irradiation with a 23 W light bulb. The introduction of protonation can modulate the surface charge of g‐C3N4; this enhances its conductivity and provides a “highway” for the delocalization of electrons. This work highlights the potential of conjugated polymers in antibacterial application.

Molybdenum (Mo)‐based materials with abundant electronic properties have been extensively studied in terms of environmental pollutant control. In photocatalysis, thermal catalysis, electrocatalysis, Fenton or Fenton‐like reactions, and other technical means, the properties of different Mo‐based materials have been fully exerted. In this review, the latest developments in Mo‐based materials in the control of water and air pollutants are summarized. In addition, possible methods are discussed to enhance the activity of Mo‐based materials to provide the direction for the design of highly efficient Mo‐based catalysts in the future.
