Abstract

Rational design of water activation center to promote active hydrogen (*H) generation and stabilize Cu(I) species are significant for the formation of multicarbon (C2+) products over Cu-based catalysts in electrocatalytic CO2 reduction reaction (CO2RR). Herein, CeO2 nanograins and CuO nanothorns were selectively deposited on the edges of Cu2O cubes through the seed-mediated growth method. The as-synthesized CuxO–CeO2 composites exhibit enhanced Faradaic efficiency and partial current density of C2H4 compared with Cu2O cubes. In situ spectroscopies and theoretical calculations confirm that the Cu–O–Ce bridges in CuxO–CeO2 composite can effectively enhance *H absorption and stabilize Cu(I) species, facilitating subsequent C–C coupling and further protonation into the key *COCHO intermediate of C2H4. This work provides new insights into modulating *H absorption and stabilizing Cu(I) species for boosting CO2 to C2+ products.

Cu- o - ce桥上活性氢吸收增强和Cu(I)稳定促进电催化CO2还原乙烯
合理设计水活化中心,促进活性氢(*H)的生成和Cu(I)的稳定,对于电催化CO2还原反应(CO2RR)中Cu基催化剂上多碳(C2+)产物的生成具有重要意义。本文通过种子介导生长的方法,将CeO2纳米颗粒和CuO纳米刺选择性地沉积在Cu2O立方体的边缘。与Cu2O立方体相比,合成的Cu2O - ceo2复合材料具有更高的法拉第效率和C2H4的偏电流密度。原位光谱和理论计算证实,CuxO-CeO2复合材料中的Cu- o - ce桥可以有效地增强*H吸收,稳定Cu(I),促进随后的C-C偶联和进一步质子化成C2H4的关键*COCHO中间体。这项工作为调节*H吸收和稳定Cu(I)物种促进CO2生成C2+产品提供了新的见解。
