The mitigation of CO₂ emission is an urgent issue to be addressed. CO₂ electroreduction into carbon-neutral fuels renders an appealing strategy to settle the anthropogenic environmental problems. In this study, silver nanocubes with 43nm in length enclosed by {111} facet were synthesized for the CO₂ electrocatalytic reduction to CO. The nanocubes exhibit excellent catalytic activity in regard to outstanding CO Faradaic efficiency with the maximum approximately 98% and eminent long-term stability. The enhanced catalytic activity may be attributed to stable low-index {111} facet of Ag nanocubes with low surface energy.

银纳米立方体作为 CO2 还原为 CO 的高性能电催化剂

减少CO ₂排放是一个亟待解决的问题。CO ₂电还原成碳中性燃料为解决人为环境问题提供了一种有吸引力的策略。在这项研究中，银纳米立方体与 43合成了由{111}晶面包围的长度为nm的CO ₂电催化还原为CO。纳米立方体在出色的CO法拉第效率方面表现出优异的催化活性，最大值约为98％，并且具有出色的长期稳定性。增强的催化活性可能归因于具有低表面能的Ag纳米立方体的稳定的低指数{111}面。
