文摘 近年来,全球范围因二氧化碳(CO_2)的过量排放导致的环境问题日益严重,引起世界各国人民的广泛关注。电化学还原CO_2转化为清洁能源和高价值化学品,不仅可以有效地缓解CO_2导致的温室效应,而且有望为解决能源危机提供重要出路。本文简述了电化学还原CO_2的反应原理,对近年报道的一些高选择性的二元金属催化剂进行分类归纳。综述了二元金属材料物质组成、原子配比、微观形貌、颗粒尺寸等物化性质对CO_2还原性能的影响规律,并对部分催化剂的选择性增强机理重点分析。最后,讨论了二元金属材料高效选择性电化学还原CO_2存在的主要问题和未来可能的研究重点。
其他语种文摘 In recent years,the global environmental problems caused by excessive emissions of carbon dioxide(CO_2)have become severe gradually,which attract widespread concern all over the world.The electrochemical reduction of CO_2to clean energy and high-value chemicals not only can effectively alleviate greenhouse effect,but also provide an alternative to solve the energy crisis.The reaction principle of electrochemical reduction of CO_2 was briefly described in this review,and some binary metal catalysts with high product selectivity reported in recent years were classified and summarized. The influences of the bimetallic materials physico-chemical properties,including element and composite,atomic ratio,microscopic morphology,particle size,etc.on CO_2 reduction performance were reviewed,and the explanation of high selectivity for partial typical catalysts derived from DFT calculation was presented.Finally,the main problems and future research challenges for the selective conversion of CO_2 on bimetallic catalysts with high efficiency were also discussed.
