摘要:

由于CO2是最重要的温室气体, 空气污染和全球变暖引起了人们对CO2转化研究的极大兴趣. 光催化CO2还原反应(CRR)是一种关键的碳捕获和利用技术, 旨在将CO2转化为燃料和化学品等有价值的产品. 然而, 用于CRR的许多半导体光催化剂面临着光吸收低、载流子分离差和电子-空穴复合等挑战, 导致反应收率低. 这些问题的一些重要解决方案包括减小纳米结构尺寸、助剂装饰以及金属/非金属掺杂和构造异质结结构. 一维(1D)纳米结构, 如纳米棒、纳米管、纳米线和纳米纤维, 由于其优异的光吸收能力、高电子-空穴分离效率、高长径比和丰富的暴露活性表面位点, 是CO2还原过程的突出光催化剂. 本文首先介绍了CO2还原机理, 随后讨论了基于生长环境的一维纳米材料生长方法及应用在光催化CRR中的类型. 综述了应用于CRR中1D基光催化剂的两种主要改进策略, 包括表面改性和构造异质结结构. 最后提出了CRR在未来应用面临的一些重要挑战及其解决方案.

Abstract:

Air pollution and global warming have aroused great interest in CO2 conversion research, as CO2 is the most important greenhouse gas. Photocatalytic CO2 reduction reaction (CRR) is a key carbon capture and utilization (CCU) technology aimed at transforming CO2 into valuable products like fuels and chemicals. However, many semiconductor photocatalysts used in CRR face challenges such as low optical absorption, poor charge carrier separation, and electron-hole recombination, leading to low reaction yields. Some important solutions to these issues include reducing nanostructure dimensions, cocatalyst decoration, as well as metal/nonmetal doping, and heterojunction construction. One-dimensional (1D) nanostructures like nanorods, nanotubes, nanowires, and nanofibers are prominent photocatalysts for CO2 reduction process due to their excellent light absorption capability, high electron-hole separation efficiency, high aspect ratio, and abundant exposed active surface sites. In this research, after studying CO2 reduction mechanism, we first discuss 1D nanomaterials growth methods based on the growing environment. Types of 1D nanostructures in photocatalytic CRR, have been also investigated. Two main strategies to improve 1D-based photocatalysts in CRR including surface modification and heterojunction construction are reviewed. Finally, the report presents some important challenges of the CRR and their solutions for future applications.
