摘要

目的

为提高火电行业排放的CO

电催化还原制甲酸（HCOOH）的效率，降低CO

在大气环境中的排放水平，

方法

本文通过分析电催化CO

还原反应（electrochemical carbon dioxide reduction reaction，ECO2RR）的途径和不同调控策略下的Bi金属基电催化效果，提出高效Bi基催化剂的改进方向。

结果

研究表明，在电解池中稳定运行时间大于100 h的情况下，Bi基催化剂可实现大于85%的法拉第效率；Bi基ECO2RR催化剂可以从表面形貌设计、表面改性、缺陷工程、组分调控4个方面进行改进。表面形貌设计可以提供更多的活性位点，但不能满足商业规模HCOOH生产的实际应用需求；表面改性可以在选择性和活性方面产生有益影响，但存在稳定性、成本、机理等问题；缺陷工程可以优化反应中电荷转移和中间体的结合强度，但缺陷的可控性和机理需要进行研究；组分调控可以从元素掺杂、合金化、异质结构构建3个方面进行，是目前优化Bi基ECO2RR反应的重要途径，但还需要补充更加贴合工业开发的检验和计算。

结论

Bi基催化剂在电还原CO

制HCOOH的工业化应用中具有突出潜力，更加深入的改进和机理研究可以加速CO

衍生化学品的工业化。

Abstract

Objective

In order to improve the efficiency of electrocatalytic reduction of CO

emitted by the thermal power industry to formic acid (HCOOH) and reduce the emission level of CO

in the atmospheric environment

Methods

In this paper

the improvement direction of high-efficiency Bi-based catalysts was proposed by analyzing the pathways of electrochemical carbon dioxide reduction reaction (ECO2RR) and the electrocatalytic effects of Bi metal-based catalysts under different control strategies.

Results

Studies have shown that Bi-based catalysts can achieve a Faraday efficiency greater than 85% when the stable operation time in the electrolytic cell is greater than 100 h. Bi-based ECO2RR catalysts can be regulated from four aspects : surface morphology design

surface modification

defect engineering and component regulation. The surface morphology design can provide more active sites

but it cannot meet the practical application requirements of commercial scale HCOOH production. Surface modification can have beneficial effects on selectivity and activity

but there are problems such as stability

cost and mechanism. Defect engineering can optimize the charge transfer in the reaction and the bonding strength of the intermediate

but the controllability and mechanism of defects need to be studied. Component regulation can be carried out from three aspects: Element doping

alloying

and heterostructure construction. It is an important way to optimize the Bi-based ECO2RR reaction

but it also needs to supplement the test and calculation that are more in line with industrial development.

Conclusion

Bi-based catalysts have outstanding potential in the industrial application of electroreduction of CO

to HCOOH.More in-depth improvement and mechanism research can accelerate the industrialization of CO

-derived chemicals.
