| 摘要: 电催化二氧化碳还原技术能够有效地将CO2转化为有价值的化学品，从而减少CO2排放，为CO2的治理提供一举两得的解决方案，并能够助力我国实现“碳达峰”和“碳中和”的碳排放目标。目前，常用的单金属纳米催化剂具有催化位点单一以及产物与中间体的吸附能调控困难等缺点，导致其在催化剂选择性、活性及稳定性等方面表现不佳。而双金属纳米催化剂由于存在2种原子配位，能够调整催化剂的电子结构，实现对中间体结合能的精细调控，并带来丰富且灵活的活性位点，从而被广泛研究。本文综述了国内外最新的双金属纳米催化剂的研究进展，主要针对双金属纳米催化剂的精细调控手段，如掺杂调控、非均相结构调控、合金化调控和几何结构调控进行了总结，对其中所存在的协同效应、应力效应和电子效应等双金属纳米催化剂的催化机理进行了阐述。在此基础上，总结了目前双金属纳米催化剂研究的不足，并对未来的研究方向与发展前景进行了展望。 |

| Abstract: Electrocatalytic carbon dioxide reduction technology can effectively convert CO2 into valuable chemicals to reduce CO2 emissions, providing a solution for CO2 management and helping China to achieve the carbon emission target of“carbon peak and carbon neutrality”. Currently, the commonly used monometallic nanocatalysts have the shortcomings of a single catalytic site and difficult regulation of the adsorption energy between products and intermediates, and face problems such as poor catalyst selectivity, activity, and stability. In contrast, bimetallic nanocatalysts have been widely studied due to the existence of two atomic coordinations, which can adjust the electronic structure of the catalyst, finely regulate the binding energy of the intermediates, and bring abundant and flexible active sites. This paper reviews the latest research progress of bimetallic nanocatalysts, mainly focusing on the fine regulation of bimetallic nanocatalysts, such as doping control, heterogeneous structure control, alloying control, and geometric structure control, and the catalytic mechanism of bimetal nanocatalysts such as synergistic effect, stress effect, and electronic effect. Moreover, the current shortcomings and future research of bimetallic nanocatalysts are discussed. |
