Abstract
Practical CO2 and CO electroreduction are often operated at elevated temperatures, yet the correlation between the temperature increase and catalytic activity and selectivity has not been well-defined. This study uncovers that higher temperatures enhance *CO coverages, but in CO2 reduction, they also promote *CO desorption to vapor-phase CO, lowering C2H4 selectivity. In CO reduction, elevated temperatures facilitate CO diffusion to overcome the unfavorable *CO adsorption thermodynamics, which promotes C—C coupling. More details are discussed in the article by Wang et al. on pages 2705—2711.
实际的二氧化碳和一氧化碳电还原通常在较高温度下进行，但温度升高与催化活性和选择性之间的相关性尚未明确。本研究发现，温度升高会提高*CO的覆盖率，但在二氧化碳还原中，温度升高也会促进*CO解吸为气相CO，从而降低C2H4的选择性。在一氧化碳还原过程中，温度升高有利于一氧化碳的扩散，克服不利的*CO吸附热力学，从而促进C-C耦合。更多详情请参见 Wang 等人的文章（第 2705-2711 页）。
期刊介绍：
The Chinese Journal of Chemistry is an international forum for peer-reviewed original research results in all fields of chemistry.
