Abstract
A novel TiO2 supported core-shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks the high coordination sites on the Pd core, and therefore pronouncedly enhances the ethylene selectivity for the catalytic hydrogenation of acetylene in excess ethylene.
摘要
通过顺序光沉积法制备了一种新型的 TiO2 负载核壳（Pd@Ag）双金属催化剂。Ag 壳有效地阻止了 Pd 核上的高配位位，因此显著提高了过量乙烯中乙炔催化加氢的乙烯选择性。
