The selective bio‐ethanol cascade transformation to hydrocarbons over multifunctional catalysts is a highly promising sustainable pathway to high‐value chemicals and fuels. However, principles to control the selectivity of the bio‐ethanol transformation using the effects of the size of nanoparticle catalysts have remainedlargely unexplored. Here, using bio‐ethanol transformation reactions catalyzed by Au/ZnZr₁₀O_x as examples, we demonstrate that changing the fashion of gold loading enables control over product distribution. Our results reveal that larger gold particles tendto show much higher selectivity for 1,3‐butadiene, whereas smaller gold nanoparticles favor the formation of acetaldehyde.This study uncovers general principles for tailoring the selectivity of bio‐ethanol transformation by carefully engineering the size of gold. It opens a new avenue for the rational design of multifunctional catalysts to enhance the production of desired reaction products in complex cascade reaction sequences.

通过调整ZnZr10Ox催化剂上载金的大小来调整生物乙醇转化的选择性

通过多功能催化剂选择性地将生物乙醇级联转化为碳氢化合物是获得高价值化学品和燃料的极有前途的可持续途径。然而，利用纳米粒子催化剂的尺寸来控制生物乙醇转化的选择性的原理尚未得到广泛探索。在这里，使用Au / ZnZr ₁₀ O _x催化的生物乙醇转化反应作为示例，我们证明了改变装金方式可以控制产品分配。我们的研究结果表明，较大的金颗粒倾向于对1,3-丁二烯具有更高的选择性，而较小的金颗粒则有利于乙醛的形成。本研究揭示了通过精心设计金的大小来调整生物乙醇转化选择性的一般原则。。它为多功能催化剂的合理设计开辟了一条新途径，以提高复杂级联反应顺序中所需反应产物的产生。
