铜基电催化剂中的晶界可提高太阳能驱动的电化学CO2还原对多碳产品的选择性。然而,在铜中形成晶界的方法仍然非常有限。近日,天津大学巩金龙教授团队使用聚乙烯吡咯烷酮(PVP)作为添加剂控制铜电沉积的晶粒生长制备了富晶界的铜催化剂(GB-Cu),并将...
For EC CO2 reduction using CuZn alloy by laser ablation in liquid [41], C2H4 and CO were the main products, while ethanol was produced in negligibly small amounts. In contrast, the Cu-Zn mixture yielded CO more dominantly than C2H4, but ethanol was also detected at meaningful levels. ...

Here, we demonstrated a rational strategy to synthesize the Cu catalyst under a CO-rich environment to induce the growth of defect-rich sites that are best for the adsorption of CO. During the electrochemical CO2 reduction process, these defect-rich sites enabled a high surface density of ...
Accordingly, the researchers first converted CO2 into CO in a membrane electrode assembly using a Ni–N–C single-atom catalyst, and then developed a grain-boundary-rich Cu (GB_Cu) catalyst for acetate production from electrochem...
