摘要

支撑在不同氧化物上的铂是苯甲醇氧化的有效催化剂，但支撑材料的类型会影响整体催化性能。在此，我们研究了 2.5-4.6 纳米分散铂粒子在可还原氧化物（TiO 2 (P25)、CeO 2、MoO 3 和  -Fe 2 O 3）和不可还原氧化物（ -Al 2 O 3）上的性能，并将其应用于液态水存在下的苄醇氧化催化剂。性能差异归因于载体从吸附在铂上的苯甲醇中接受氢的能力和以水的形式去除表面羟基的能力。

Influence of the oxidic support material on the platinum-catalyzed benzyl alcohol oxidation

Platinum supported on different oxides is an effective catalyst for the benzyl alcohol oxidation, but the type of support material affects the overall catalytic performance. Here, the performance of dispersed platinum nanoparticles in range of 2.5-4.6 nm supported on reducible oxides (TiO 2 (P25), CeO 2 , MoO 3 and  -Fe 2 O 3 ) and an irreducible oxide(  -Al 2 O 3 ) is investigated for the application of benzyl alcohol oxidation catalysts in the presence of liquid water. The difference in the performance is attributed to the ability of the support to accept hydrogen from benzyl alcohol adsorbed on platinum and the ability to remove surface hydroxyl groups in the form of water.
