A proficient heterogeneous catalytic system for the photocatalytic N-formylation reaction of amines and cyclic carbonate synthesis from epoxides using CO₂ as a carbon source under ambient reaction conditions has been documented. A sophisticated approach has been established for the current photocatalytic process, aiming for the successful production of formamides and cyclic carbonates with high levels of selectivity and efficiency by adjusting several variables such as the solvent, time, as well as light source involved in the reaction. We have synthesized two distinct catalysts, T-COF and N-COF, along with the g-C₃N₄ heterojunction, demonstrating outstanding photocatalytic performance. Compared to g-C₃N₄@N-COF, the g-C₃N₄@T-COF photocatalyst showed significantly better catalytic efficiency in the light-driven formation of cyclic carbonates and formamides using CO₂ under other suitable reaction conditions at room temperature. The g-C₃N₄@COF photocatalysts can be recycled and used multiple times without any noticeable decrease in the efficiency.

使用共价有机框架/g-C3N4 复合材料利用光介导的二氧化碳固定对胺进行光化学 N-甲酰化和环氧化物碳酸盐合成


已经记录了一种熟练的非均相催化系统，用于在环境反应条件下使用 CO₂ 作为碳源从环氧化物中进行胺的光催化 N-甲酰化反应和环状碳酸盐合成。已经为当前的光催化过程建立了一种复杂的方法，旨在通过调整反应中涉及的溶剂、时间和光源等多个变量，成功生产具有高选择性和效率的甲酰胺和环状碳酸盐。我们合成了两种不同的催化剂，T-COF 和 N-COF，以及 g-C₃N₄ 异质结，表现出优异的光催化性能。与 g-C₃N₄@N-COF 相比，g-C₃N₄@T-COF 光催化剂在室温下其他合适的反应条件下使用 CO₂ 光驱动形成环状碳酸盐和甲酰胺时表现出显着更好的催化效率。g-C₃N₄@COF 光催化剂可以回收和多次使用，而不会显着降低效率。
