In this work, we explored a post-synthetic modification of the well-known graphitic carbon nitride (g-CN) by means of an “amorphization” treatment and evaluate the resulting change in photocatalytic activity towards the synthesis of valuable perfluoroalkyl derivatives. The as-prepared “super-amorphous” CN (SACN) exhibits a significant increase of the photocatalytic activity (up to a six-fold enhancement with the optimum structure with respect to g-CN), which originates from the lower degree of crystallinity of the CN and its reduced bandgap. The SACN photocatalysts display versatility and good tolerance towards functional group variations of the reagents, emerging as a potential new benchmark CN structure for heterogeneous organic photocatalysis.

石墨氮化碳的定制非晶化触发了优异的光催化 C-C 偶联以合成全氟烷基衍生物

在这项工作中，我们通过“非晶化”处理探索了众所周知的石墨氮化碳（g-CN）的合成后改性，并评估了光催化活性对合成有价值的全氟烷基衍生物的变化。所制备的“超无定形”CN (SACN) 表现出光催化活性的显着提高（对于 g-CN 的最佳结构提高了 6 倍），这源于较低的结晶度CN 及其减小的带隙。SACN 光催化剂显示出多功能性和对试剂官能团变化的良好耐受性，成为非均相有机光催化的潜在新基准 CN 结构。
