报道了以SiO_2、ZnO、γ-Al_2O_3、CeO_2为载体的Pt纳米粒子催化糠醛选择性液相加氢制糠醇的反应。环境氢气压力和低至50 ° C的温度显示足以驱动糠醛氢化，具有高转化率和>99%的对糠醇的选择性。强烈的支持和溶剂的依赖性进行观察，与甲醇和正丁醇证明优良的溶剂，促进高糠醇收率超过均匀分散的4纳米Pt纳米粒子在MgO，CeO 2和γ-Al 2 O3。相反，非极性溶剂赋予差的糠醛转化率，而乙醇有利于缩醛副产物的形成。通过控制氧化物载体、反应溶剂和反应温度可以实现糠醛选择性加氢。(C)2015 Elsevier B. V.版权所有。
The selective liquid phase hydrogenation of furfural to furfuryl alcohol over Pt nanoparticles supported on SiO2, ZnO, gamma-Al2O3, CeO2 is reported under extremely mild conditions. Ambient hydrogen pressure, and temperatures as low as 50 degrees C are shown sufficient to drive furfural hydrogenation with high conversion and >99% selectivity to furfuryl alcohol. Strong support and solvent dependencies are observed, with methanol and n-butanol proving excellent solvents for promoting high furfuryl alcohol yields over uniformly dispersed 4 nm Pt nanoparticles over MgO, CeO2 and gamma-Al2O3. In contrast, non-polar solvents conferred poor furfural conversion, while ethanol favored acetal by-product formation. Furfural selective hydrogenation can be tuned through controlling the oxide support, reaction solvent and temperature. (C) 2015 Elsevier B.V. All rights reserved.
