Dichloromethane electrochemical dechlorination to chloromethane is a promising and economical strategy but remains a critical challenge due to the low selectivity of chloromethane and catalyst deactivation. In this paper, an efficient and selective CuMn2O4 nanofiber is prepared by electrospinning and then used in aromatic chloride formation and selective dechlorination of dichloromethane to chloromethane. Experimental and characterization results unveil that the CuMn2O4 nanofiber with a one-dimensional (1D) nanostructure, large specific surface area, and high catalytic activity exhibits the most superior chloromethane production (387.46 μmol), high chloromethane selectivity (97.27%), and excellent stability. The coupling system of dichloromethane dechlorination with benzaldehyde chlorination not only produces chlorobenzaldehyde and chloromethane with high economic value but also explores the dichloromethane dechlorination to produce the chloromethane mechanism. Therefore, it provides a promising route and a more stable, active, and selective catalyst for the production of valuable chloromethane.

电纺 CuMn2O4 尖晶石纳米纤维作为电催化剂用于生产氯甲烷和芳香氯化物
二氯甲烷电化学脱氯生成氯甲烷是一种有前途且经济的策略，但由于氯甲烷的选择性低和催化剂失活，仍然是一个严峻的挑战。本文采用静电纺丝法制备了高效、选择性的CuMn 2 O 4纳米纤维，并将其用于芳香氯化物的形成和二氯甲烷选择性脱氯制氯甲烷。实验和表征结果表明，具有一维（1D）纳米结构、大比表面积和高催化活性的CuMn 2 O 4纳米纤维表现出最优异的氯甲烷产量（387.46 μmol）、高氯甲烷选择性（97.27%）、和优良的稳定性。二氯甲烷脱氯与苯甲醛氯化耦合系统不仅生产出经济价值较高的氯苯甲醛和氯甲烷，而且探索了二氯甲烷脱氯生产氯甲烷的机理。因此，它为生产有价值的氯甲烷提供了一条有前途的路线和一种更稳定、活性和选择性更高的催化剂。
