Hydrogen-bonded organic frameworks (HOFs) provide a platform to self-assemble numerous functional species into an ordered structure. Herein, a well-known photoactive C3N4 moiety was integrated into an HOF structure (PFC-42) with the merits of high porosity and crystallinity. Under visible-light irradiation, the Pt nanoparticle-loaded PFC-42 (PFC-42-Pt) continuously produces hydrogen from water in the presence of scavengers with the evolution rate of 11.32 mmol g−1, which is outstanding among all the reported Pt/porous composite materials. The significantly high H2 evolution of PFC-42-Pt compared with that of amorphous analogue bulk C3N4–Pt and nanosheet C3N4–Pt demonstrates that the ordered arrangement of photosensitizers dramatically improves the photocatalytic activity of the material, which is further proved by the recrystallization experiment. This study represents the first example of HOF capable of photocatalysis, not only demonstrating the great application potentials of HOF in heterogeneous photocatalysis but also rendering an excellent opportunity to reveal structure–activity relations.

将活性C3N4部分整合到氢键有机骨架中以进行有效的光催化
氢键有机骨架（HOF）提供了一个平台，可将众多功能物种自组装为有序结构。此处，具有高孔隙率和结晶度的优点是将众所周知的光敏C 3 N 4部分整合到HOF结构（PFC-42）中。在可见光照射下，负载有Pt纳米颗粒的PFC-42（PFC-42-Pt）在清除剂存在下连续从水中产生氢，其释放速率为11.32 mmol g -1，在所有报告的Pt中均表现出色/多孔复合材料。与无定形类似物本体C 3 N 4 -Pt和纳米片C 3 N相比，PFC-42-Pt的H 2放出量显着高4 –Pt证明光敏剂的有序排列可以显着提高材料的光催化活性，重结晶实验进一步证明了这一点。这项研究代表了能够进行光催化的HOF的第一个例子，不仅证明了HOF在非均相光催化中的巨大应用潜力，而且为揭示结构-活性关系提供了绝佳的机会。
