摘要:

光催化还原CO2的基本原理是当入射光能量大于或等于半导体的禁带宽度时,其价带中的电子将受激发跃迁到导带,于导带发生还原反应,光催化还原CO2是解决能源危机和环境污染的新技术之一。本文通过CO2拟人化方式,以CO2分子变形的经历介绍光催化还原CO2转化为碳一产物的反应途径与机理,介绍了各产物在生活中的应用。

关键词: 光催化, CO2还原, 碳一产物

Abstract:

When incident light energy is greater than or equal to the forbidden bandwidth of a semiconductor, the electrons in its valence band will be excited to the conduction band, and a reduction reaction will occur. This is the basic principle of the photocatalytic reduction of CO2. In this paper, we introduce the reaction mechanism of the photocatalytic reduction of CO2 into C1 products, and we describe the potential applicability of each product.

Key words: Photocatalysis, CO2 reduction, C1 products
