The adjustable intermediate binding capacity in electrocatalytic carbon dioxide (CO₂) reduction is critical for varying the reaction pathways to desired products. Herein, we first report the synthesis of boron-doped amorphous zinc oxide with (B-a-ZnO-Sb) or without antimony nanoparticles embedding (B-a-ZnO) via one-step wet chemical method, which is easy to scale up by enlarging the vessel and increasing feeding. Sb successfully realizes the product switching from CO on B-a-ZnO to formate on B-a-ZnO-Sb. Both experimental and theoretical results reveal that Sb weakens the charge interaction on Zn atoms. Based on the moderate adsorption of ⋆COOH and strong adsorption of ⋆OCHO and ⋆HCOOH for B-a-ZnO, the foreign Sb weakens the adsorption of these intermediates and brings about a favor formate production instead of CO. This work points out a new direction for the synthesis of amorphous ZnO-based catalysts and provides advanced insights into the aimed selectivity switch for CO₂ reduction by electronic effect.

电催化二氧化碳（CO ₂) 减少对于改变所需产品的反应途径至关重要。在此，我们首先报道了通过一步湿化学法合成具有（Ba-ZnO-Sb）或不具有锑纳米粒子嵌入（Ba-ZnO）的硼掺杂非晶氧化锌，该方法易于通过扩大容器进行放大和增加喂养。Sb成功实现了从Ba-ZnO上的CO到Ba-ZnO-Sb上的甲酸盐的产物转换。实验和理论结果均表明，Sb 削弱了 Zn 原子上的电荷相互作用。基于Ba-ZnO对⋆COOH的适度吸附和对⋆OCHO和⋆HCOOH的强吸附，外来Sb削弱了这些中间体的吸附，有利于甲酸盐的产生而不是CO。₂电子效应还原。
