摘要：

在过去的几十年里，二氧化碳(CO2)电化学还原技术的迅猛发展越来越引起国际国内的广泛关注。此技术可以利用太 阳能、风能、潮汐能等可再生能源及核电/水电的弃电，将温室气体CO2还原为低碳燃料和有经济价值的化学品。这一技术 可以促进废弃物(气体)利用以实现能源储存与转换，变废为宝，被认为是一种绿色环保、有发展潜力的CO2处置方法。使用的催化剂和电解质不同，CO2电化学还原过程给出的产物也不尽相同。本文概述了CO2电化学还原的原理以及催化剂、电解
质和反应器的发展现状。

关键词: CO2电化学还原, 催化剂, 电解质, 反应器

Abstract:

 Over the past decades, electrochemical reduction of CO2 (ERC) has received widespread attentions due to its ability to store renewable energy from solar, wind, tidal and so on as well as abandoned electricity energy nuclear/hydroelectricity power plants in the forms of low-carbon fuels and valuable chemicals. This technology can promote energy storage and the utilization of waste (gas). It is considered to be a green and promising CO2 disposal method. When using different catalysts, electrolytes and reactor design for ERC, the products and system energy efficiency obtained would be different. Here, we give a brief overview of the ERC fundamentals and the current state of this technology.

Key words:  ERC, catalyst, electrolyte, reactor
