The cover picture shows a new one step approach to synthesize g‐C 3 N 4 nano‐sheets by direct thermal pyrolysis process of urea in NH3 atmosphere. For the first time, the influence of the preparation gas atmosphere on the composition, crystalline and polymerization degree, and the photocatalytic activity of the g‐C 3 N 4 synthesized from thermal condensation of urea was investigated. Furthermore, we studied in depth the structure‐performance relationship in the system, and it was found that the synergistic effect of the larger surface area, the adjusted band energy structure and the well crystallization may be conductive to the higher separation of the electron‐ hole pair, thus leading to the wonderful performance for the g‐C 3 N 4 ‐NH 3 . Notably, the method has the merits of low cost, scalable production and environmental friendliness. More details are discussed in the article by Dai et al. on page 173–182.
