摘要:

随着日益增长的能源需求,人类社会对于传统碳基化石能源过度依赖,不仅加速了地球上有限能源储备的消耗,还导致大气中二氧化碳(CO2)不断累积。如何对二氧化碳进行可持续的捕获再利用,实现高效的零碳网络循环,已成为人类亟需解决的重大挑战之一。近年来,使用绿色可持续电力的电化学二氧化碳还原反应(CO2RR)生产增值化学品成为研究热点。本文首先介绍了CO2RR的基本电化学反应原理;然后总结了电化学还原CO2制备甲酸/甲酸盐的主要金属基催化剂,着重介绍了Bi、Sn、In三类金属基催化剂的设计调控策略;进一步概括了电化学相关的原位表征手段,分别介绍了原位光谱技术和原位X射线表征技术;最后对电催化二氧化碳还原研究领域的未来发展进行了展望。

Abstract:

With the ever-increasing energy demand, human society is over-reliant on traditional carbon-based fossil energy, which not only accelerates the consumption of the earth's limited energy reserves, but also leads to the continuous accumulation of carbon dioxide (CO2) in the atmosphere. How to sustainably capture and reuse CO2 and achieve an efficient zero-carbon network cycle has become one of the major challenges that human beings urgently need to solve. In recent years, electrocatalytic CO2 reduction reaction (CO2RR) production of value-added chemicals using green sustainable electricity has become a research hotspot. In this review, we firstly introduce the basic electrochemical reaction principle of CO2RR. Then we summarize the main metal-based catalysts for the electrochemical reduction of CO2 to prepare formic acid/formate, and focus on the design and regulation strategies of three metal-based (Bi, Sn and In) catalysts. In addition, we generalize the in situ characterization methods related to CO2RR, including in situ spectroscopic techniques and in situ X-ray characterization technique. Finally, the future opportunities and challenges for the electrocatalytic CO2 reduction are prospected.

Key words: carbon dioxide, electrocatalytic reduction, formic acid, metal-based catalyst, in situ characterization
