Abstract
resources. The development of high-performance electrocatalysts to complete this process more efficiently is of great significance to sustainable development. Owing to their unique structural characteristics, single-atom catalysts are expected to promote the reaction process more efficiently. In this study, an atomically dispersed Cu species on N-doped carbon nanosheet composite material (Cu-N-C) was prepared by metal-organic framework derivatization. Compared with traditional Cu bulk electrodes, the Cu-N-C material has better catalytic performance for the synthesis of methyl N-phenylcarbamate; and the optimized yield reached 71 % at room temperature and normal pressure. The Cu-N-C material has good stability that the catalytic performance does not decrease after repeated use for 10 times. In addition, the Cu-N-C material has good applicability to this catalytic system, and a variety of amines can be smoothly converted into corresponding carbamates.
