摘要

本文提出的一种用于选择性乙炔加氢的 PdAu/Al2O3 蛋壳催化剂结合了两个因素以提供完美的性能：用金隔离 Pd1 活性位点以及活性相在催化剂颗粒上的蛋壳分布。PdAu/Al2O3 催化剂在 Pd 催化剂的水平上表现出较高的乙炔氢化活性，在 Au 催化剂的水平上表现出较高的内在乙烯选择性。

Performance of PdAu/Al2O3 egg-shell catalyst with isolated Pd1 sites for selective hydrogenation of acetylene

A herein proposed PdAu/Al₂O₃ egg-shell catalyst for selective acetylene hydrogenation combines two factors to provide perfect performance: isolation of Pd₁ active sites by Au and an egg-shell distribution of the active phase across the catalyst pellets. The PdAu/Al₂O₃ catalyst exhibits high acetylene hydrogenation activity at the level of Pd-catalysts and high intrinsic ethylene selectivity of Au-catalysts.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
