Electrochemical reduction of CO₂ to value-added chemicals is a promising strategy for making use of excess CO₂. Here, we synthesized a porous network zinc catalyst by electrodeposition of Zn(NO₃)₂ on Zn foil. The material exhibited excellent catalytic activity, being able to reduce CO₂ to CO with ~80% Faradaic efficiency (FE_CO) at −1.1 V vs RHE. Control experiments suggested that the high activity of the Zn porous network can be attributed to its unique nanostructured surface with a large active surface area.

在电沉积锌多孔网络上将CO ₂有效电催化还原为CO

用电化学方法将CO ₂还原为增值化学品是利用过量CO _2的一种有前途的策略。在这里，我们通过在锌箔上电沉积Zn（NO ₃）₂合成了多孔网络锌催化剂。该材料表现出出色的催化活性，在相对于RHE的-1.1 V下能够以〜80％的法拉第效率（FE _CO）将CO ₂还原为CO 。对照实验表明，Zn多孔网络的高活性可以归因于其独特的具有大活性表面积的纳米结构表面。
