Abstract:

The electrochemical reduction of carbon dioxide (ECO2RR) presents a significant value for carbon neutrality by preparing high-energy chemicals or fuels from renewable energy. Particularly, ECO2RR using copper-based catalysts, with their advantages of low cost and excellent catalytic activity, has emerged as the most promising strategy. In this paper, the research progress of copper-based catalysts in the preparation of formic acid in recent years is comprehensively summarized. The adjusting strategies of ECO2RR to formic acid include morphology, surface valence, alloying, crystal plane effect, vacancy and carbon carrier. The effects of the number of active sites and the formation of key intermediate *OCHO on the selectivity of formic acid products are discussed. Finally, the challenges faced in this field and the prospects from the perspectives of in-situ characterization, scientific calculation and reaction condition optimization are summarized.

Key words: electrocatalysis, carbon dioxide reduction, Cu-based catalyst, formic acid

摘要:

电化学二氧化碳还原(ECO2RR)通过可再生能源制备高能量化学品或燃料对碳中和具有巨大价值。尤其是以铜基催化剂进行的ECO2RR,其成本优势和卓越的催化活性使其成为最有前景的策略。在ECO2RR的各种产物中,甲酸作为优秀的储氢材料和内燃机燃料展现出工业化生产潜力。本文针对近年来过渡金属族的铜基催化剂在制备甲酸的研究进展进行了全面的总结,从ECO2RR制甲酸机理出发,综述了铜基催化剂在ECO2RR制甲酸领域取得的重要研究进展,其中以典型催化剂为例分析ECO2RR生成甲酸的策略,包括形貌结构、表面价态、合金化、晶面效应、空位和碳载体等,重点讨论了活性位点数量以及关键中间体*OCHO的形成对甲酸产物选择性的影响,最后总结了该领域面临的挑战以及从原位表征、科学计算和反应条件等角度的展望。
