Abstract

Developing highly selective and stable catalysts for acetylene hydrogenation is an imperative task in the chemical industry. Herein, core-shell Pd@carbon nanoparticles supported on carbon nanotubes (Pd@C/CNTs) were synthesized. During the hydrogenation of acetylene, the selectivity of Pd@C/CNTs to ethylene was distinctly improved. Moreover, Pd@C/CNTs showed excellent stability during the hydrogenation reaction.

摘要

开发高选择性和稳定性的乙炔加氢催化剂是化学工业中的一项重要任务。本文合成了负载在碳纳米管上的核壳型钯@碳纳米粒子（Pd@C/CNTs）。在乙炔加氢反应中，Pd@C/CNTs 对乙烯的选择性明显提高。此外，Pd@C/CNTs 在加氢反应中表现出优异的稳定性。
