摘要

在苯甲醚加氢脱氧反应中合成、表征和测试了以 SBA-15 为载体的 Ni、Pt 和 NiPt 催化剂，以确定金属性质对苯甲醚芳环氢化和环己基甲基醚中间体 C-O 键氢解催化活性的影响。催化剂中的金属含量分别为 5 wt% 的 Ni 和 1 wt% 的 Pt。双金属 NiPt/SBA-15 催化剂在氢化和氢解过程中都表现出了最高的催化活性，这归功于铂对氧化镍还原的促进作用，以及形成了金属纳米颗粒分散性更好的 Ni-Pt 合金。

A comparison of Ni, Pt, and NiPt catalysts supported on SBA-15 in anisole hydrodeoxygenation: Exploring the effect of platinum addition to a nickel catalyst

Ni, Pt, and NiPt catalysts supported on SBA-15 were synthesized, characterized, and tested in anisole hydrodeoxygenation to determine the effect of the metal’s nature on the catalytic activity in the hydrogenation of the aromatic ring of anisole and hydrogenolysis of the C–O bond in the cyclohexyl methyl ether intermediate. Metal loadings in the catalysts were 5 wt% of Ni and 1 wt% of Pt. The bimetallic NiPt/SBA-15 catalyst showed the highest catalytic activity in both hydrogenation and hydrogenolysis, attributed to the promotional effect of Pt on NiO reduction and the formation of a Ni–Pt alloy with better dispersion of metal nanoparticles.
