金属纳米簇在CO2光催化还原中的研究进展

化石燃料的大量燃烧不仅造成能源危机，而且排放的二氧化碳（CO2）会使气候变暖。以清洁、储量丰富的太阳光作为能量来源，将CO2光催化还原为高附加值的化学产品是缓解当前环境问题和能源问题的主要方法之一。然而，CO2在常温常压下非常的稳定，因此需要设计并构筑高效光催化剂来捕捉和转化CO2，以达到高效光催化CO2还原的目的。在众多研究的光催化剂中，金属纳米簇因其具有独特的结构特点、优异的物理和化学性质，所以在光催化CO2还原领域得到了广泛的应用。基于此，我们首先对金属纳米簇进行了分类，将其分为贵金属纳米簇和非贵金属纳米簇；然后分别对贵金属和非贵金属纳米簇在光催化CO2还原中的研究进展进行了归纳与总结。本文通过及时全面概述近几年该领域的研究进展，从而为未来研究方向提供新思路。

Research progress of carbon dioxide photoreduction based on the catalyst of metal nanoclusters

The massive burning of fossil fuels not only causes an energy crisis, but also emits carbon dioxide (CO2) that warms the climate. Using clean and abundant sunlight as an energy source, photocatalytic reduction of CO2 into high value-added chemical products is one of the main ways to alleviate current environmental and energy problems. However, CO2 is very stable at room temperature and pressure, so it is necessary to design and build efficient photocatalysts to capture and transform CO2 to achieve the purpose of efficient photocatalytic CO2 reduction. Among the photocatalysts studied, metal nanoclusters have been widely used in the field of photocatalytic CO2 reduction because of their unique structural characteristics and excellent physical and chemical properties. Based on this, we first classify metal nanoclusters into noble metal nanoclusters and non-precious metal nanoclusters. Then, the research progress of noble metal and non-noble metal nanoclusters in photocatalytic CO2 reduction was summarized. This paper summarizes the research progress in this field in a timely and comprehensive manner and provides new ideas for future research.
