摘    要:采用溶剂热法制备了5%Pt/C、5%Ru/C和5%Ru95Pt5/C三种催化剂。对催化剂的形貌和活性组分分布进行了表征分析,分别研究了不同催化剂在苯乙炔或4-硝基酚加氢反应中的催化性能。结果表明,由于协同效应,双金属负载的催化剂5%Ru95Pt5/C比单金属催化剂具有更好的催化加氢性能。在苯乙炔加氢反应中,5%Ru95Pt5/C具有更高的选择性和优异的活性;在4-硝基酚的加氢中,5%Ru95Pt5/C的催化活性显著增加,且在循环5次后,仍保留了>99%的活性。

关 键 词:双金属  催化加氢  苯乙炔  4-硝基酚  选择性

Abstract:In this paper, 5%Pt/C, 5%Ru/C and 5%Ru95Pt5/C were prepared by a solvent thermal method. Their morphology and composition distribution were characterized and analyzed. The catalytic performance of the catalysts in hydrogenation of phenylacetylene and 4-nitrophenol were studied. The results showed that 5%Ru95Pt5/C had better catalytic performance of hydrogenation than the other two monometallic catalysts because of synergistic effect. In the hydrogenation of phenylacetylene, 5%Ru95Pt5/C had higher selectivity and more excellent activity than other two catalysts. In the hydrogenation of 4-nitrophenol, the catalytic activity of 5%Ru95Pt5/C was significantly increased, and it remained >99% activity after 5 cycles.
Keywords:bimetallic  catalytic hydrogenation  phenylacetylene  4-nitrophenol  selectivity
