Abstract:

Using electrocatalytic methods to reduce CO2 to high value-added chemicals under normal temperature and pressure is one of the ideal choices for solving the current energy shortage and environmental pollution problems. To date, copper based materials have been confirmed to be the most effective catalysts for reducing CO2 to hydrocarbon products such as methane, ethene, and ethanol. Therefore, extensive attentions have been paid to explore Cu-based electrocatalyst for CO2 reduction. In this paper, we reviewed the development of Cu-based catalysts for electrochemical CO2 reduction, and mainly focused on the dependence of catalytic performance on catalyst morphology including grain boundaries, surface structures and open facets and testing conditions such as substrate transport and local pH. Finally, we offer some challenges and perspectives on the future outlook for electrochemical CO2 reduction.

摘要:

通过电催化方法,在常温、常压下将CO2还原为高附加值化学品,是解决目前能源短缺和环境污染问题的理想选择之一。铜基材料是目前被证实的还原CO2生成烃类、醇类等高附加值产物的最有效非均相电催化剂,因此受到国内外研究者的广泛关注。综述了纳米Cu材料在电催化还原CO2领域的研究进展,重点阐述催化剂结构(晶界、表面结构与晶面、孔结构等)与性能关系,并讨论了测试条件如传质、局部pH对催化性能的影响,最后论述了该领域目前存在的问题和未来发展趋势。
