采用可控表面反应法制备了不同锡含量的PtSn双金属催化剂，并用于糠醛液相加氢反应。所有研究的系统允许以高选择性（96-98%）获得呋喃醇。当使用醇溶剂时，检测到少量产物，其来自于糠醇与溶剂之间的反应。非醇类和非极性溶剂使催化剂活性急剧下降，连续加氢反应中，催化剂失活（第一次和第三次循环之间失活25%），但对糠醇仍有很高的选择性。最有效的系统是具有最低锡含量（PtSn 0.3）的催化剂。(C)2009爱思唯尔有限公司版权所有。
Bimetallic PtSn catalysts, containing different amounts of tin, were obtained by means of controlled surface reactions and used in the liquid-phase hydrogenation of furfural. All the Studied systems allowed to obtain fufuryl alcohol with high selectivity (96-98%). A minor product was detected when alcoholic solvent were employed, coming from the reaction between furfuryl alcohol and the solvent. Nonalcoholic and non-polar solvents caused a drastic activity decrease.When used in consecutive hydrogenation reactions, the bimetallic catalysts showed a certain deactivation (25% between the first and third cycle), but still they were very selective to furfuryl alcohol. The most efficient system was the catalyst with the lowest tin content (PtSn0.3). (C) 2009 Elsevier B.V. All rights reserved.
