Front Cover: Regulating Intermediate Concentration to Synthesize Highly Crystalline g‐C₃N₄ under Spontaneous Ultrahigh Pressure (ChemNanoMat 11/2023)

Improving crystallinity of g-C3N4 is a key approach to promote charge separation and transfer to overcome its shortcomings such as easy recombination of photogenerated charges and low carrier mobility. Here highly crystalline g-C3N4 is obtained by regulating intermediate concentration under spontaneous ultrahigh pressure and thus the charge transfer is greatly boosted. Correspondingly, the photocatalytic electrons can be improved by about 12.5 times, confirming the key role of intermediate concentration on polymerization and crystallinity. This study is important for the intrinsic photocatalytic property of g-C3N4. More information can be found in the Research Article by Yinsong Si et al.
