Abstract

Atomically dispersed Pt species supported on FeO (Pt/FeO) are successfully constructed by a simple ball milling process. In the selective hydrogenation of cinnamaldehyde (CAL), Pt/FeO achieves an excellent cinnamyl alcohol (COL) selectivity of 81.7% at a CAL conversion of 91.2% in pure water medium due to the superior dissociation ability of H and preferential adsorption of CAL CO.

摘要

通过简单的球磨工艺成功构建了负载在FeO上的原子分散Pt物种（Pt/FeO）。在肉桂醛（CAL）的选择性加氢反应中，由于H的优异解离能力和CAL CO的优先吸附，Pt/FeO在纯水介质中，当CAL转化率为91.2%时，实现了81.7%的优异肉桂醇（COL）选择性。
