摘要

本研究成功开发了一种负载Bi2S3纳米片的有序介孔铈碳材料（Bi2S3@OM-CeO2-C），该材料对甲酸（FEHCOOH）的法拉第效率在相当宽的电位范围内超过90%，且运行稳定。受限制的介孔结构和界面电子转移协同促进关键中间体*OCHO的稳定生成，从而实现高效的CO2电还原为HCOOH。

Ordered mesoporous structure-based nano-confined Bi2S3@OM-CeO2-C hybrid catalyst for enhanced CO2 electroreduction to formic acid

This study successfully developed a Bi2S3 nanosheet-loaded ordered mesoporous ceria-carbon material (Bi2S3@OM-CeO2-C), which exhibits a Faradaic efficiency for formic acid (FEHCOOH) exceeding 90% over a rather wide potential range, with stable operation. The confined mesoporous structure and interfacial electron transfer synergistically promote the stable generation of the key intermediate *OCHO, thereby achieving efficient CO2 electroreduction to HCOOH.
