Abstract This work reports the preparation of Pt/TiO2-ZrO2-supported catalysts and their application in the catalytic hydrogenation of styrene oxide as a new alternative method for obtaining 2-phenylethanol. The TiO2-ZrO2 catalytic support was prepared using the sol-gel procedure with subsequent impregnation with a solution of chloroplatinic acid to obtain 1%, 2%, and 3% molar percentages of platinum and then calcinated at 400 °C. N2 adsorption-desorption, x-ray diffraction, FTIR and x-ray photoelectron spectroscopies, scanning and high-resolution transmission electron microscopies, were used to characterize the catalysts. FTIR-Pyridine adsorption and temperature-programmed desorption of ammonia methods were performed to determine the surface acidity. The surface area of the catalysts decreased slightly due to the addition of platinum, and all catalysts showed mostly the anatase crystalline phase. The catalysts consisted of nanoparticle agglomerates. 2-Phenylethanol and 2-phenylacetaldehyde were the reaction products. High selectivity to 2-phenylethanol was achieved using the 1%Pt/TiO2-ZrO2 catalyst that contained less platinum and 60 °C as the ideal temperature.

使用 Pt/TiO2-ZrO2 负载催化剂的氧化苯乙烯加氢反应生产 2-苯基乙醇

摘要 本工作报告了 Pt/TiO2-ZrO2 负载催化剂的制备及其在氧化苯乙烯催化加氢中的应用，作为获得 2-苯基乙醇的新替代方法。TiO2-ZrO2 催化载体使用溶胶-凝胶法制备，随后用氯铂酸溶液浸渍以获得 1%、2% 和 3% 摩尔百分比的铂，然后在 400°C 下煅烧。N2 吸附-解吸、X 射线衍射、FTIR 和 X 射线光电子能谱、扫描和高分辨率透射电子显微镜被用来表征催化剂。FTIR-吡啶吸附和氨的程序升温解吸方法用于确定表面酸度。由于铂的加入，催化剂的表面积略有下降，并且所有催化剂主要显示锐钛矿晶相。催化剂由纳米颗粒团聚体组成。2-苯基乙醇和2-苯基乙醛是反应产物。使用含较少铂的 1% Pt/TiO2-ZrO2 催化剂和 60 °C 作为理想温度实现了对 2-苯基乙醇的高选择性。
