In Situ Liquid‐Phase Growth Strategies of g‐C₃N₄Solar‐Driven Heterogeneous Catalysts for Environmental Applications

Liquid‐phase growth strategies have received considerable attention as a promising method for the in situ synthesis of heterostructures owing to their unique advantages such as precise microstructure control, high productivity, low cost, and high stability. In situ liquid‐phase growth methods have been utilized in the synthesis of various graphitic carbon nitride (g‐C 3 N 4 )‐based heterogeneous nanostructures to improve the separation efficiency of photogenerated electron–hole pairs by rapid charge transfer at the interfaces. Herein, recent in situ strategies for the liquid‐phase growth of g‐C 3 N 4 heterogeneous photocatalysts are summarized. The photocatalytic performance for the pollutant degradation and energy fuel production of these heterogeneous catalysts is discussed. Finally, the perspectives and opportunities on the challenges and future directions of the in situ liquid‐phase growth strategy of building heterogeneous nanostructures with a strongly connected interface are presented.
