Abstract
Octahedral Cu nanocrystals in the size range of 75-310 nm are synthesized and investigated for electrochemical CO2 reduction. The smallest nanocrystals show the best selectivity for CO2, particularly methane, which is explained by geometric effects.
摘要
合成了尺寸范围为75-310nm的八面体铜纳米晶体，并对其进行电化学二氧化碳还原研究。最小的纳米晶体对二氧化碳，尤其是甲烷表现出最佳的选择性，这可以用几何效应来解释。
