摘要本文通过对Pt/CeO2催化剂还原处理,形成足够的Pt-CeO2界面,考察了其对丙酮气相加氢制备异丙醇的性能。实验证实,Pt或CeO2位点均不能催化此反应,虽然Pt能解离氢气,CeO2能吸附丙酮。但是Pt/CeO2能够同时具备活化氢气和吸附丙酮的性能,所以催化性能大幅提高。 Sufficient Pt-CeO2 interface is formed after H2-reduction treatment of Pt/CeO2 catalyst, and its catalytic performance of acetone hydrogenation is investigated. The sole Pt or CeO2 site couldn’t catalyze acetone hydrogenation successfully, although Pt could activate H2 and CeO2 adsorb acetone. However, Pt/CeO2 could catalyze acetone hydrogenation effectively due to its excellent H2 activation and acetone adsorption ability.
