纳米金、银电催化CO2还原的载体效应
Support effect electrocatalytic CO2 reduction with gold and sliver nanoparticles
本文通过种子生长法制备了Au、Ag纳米颗粒并将其负载在不同载体上，研究了载体和粘结剂对纳米Au、Ag电催化CO2还原的影响。结果发现，负载在碳布上不加粘结剂的Au纳米颗粒在-0.75V vs RHE时，对CO表现出83.5%的法拉第效率；相比之下，负载在玻碳上加粘结剂的Ag纳米颗粒在-1.2V vs RHE时，对CO表现出75.8%的法拉第效率。相同的是，负载在碳布上不加粘结剂的Au、Ag纳米颗粒表现出更高的电流密度。

In this paper, Au and Ag nanoparticles were prepared by a seed growth method and loaded on different supports including carbon cloth and glassy carbon. The effects of the support and binder on the electrocatalyticCO2 reduction over Au and Ag nanoparticles were studied. The results show that Au nanoparticles loaded on carbon cloth without any binder exhibit ahighest Faraday efficiency of 83.5% for CO at -0.75V vs RHE.Whereas Ag nanoparticles loaded with a binder on glassy carbon display the highest Faraday efficiency of 75.8% for CO at -1.2V vs RHE. On the other hand, Au and Ag nanoparticles bear the similarity in delivering a higher current density, when being loaded on carbon cloth without binders, thantheir corresponding counterparts.
