木质素单体愈创木酚的加氢脱氧是在酸性基质负载的贵金属双功能催化剂上进行的。利用酸位测量依赖的催化结果阐明了金属纳米粒子和酸性载体的催化作用，这表明金属负责芳环的氢化，而金属沉积的酸性载体对于含氧物的脱氧是不可或缺的。在金属和载体的各种组合中，Rh/SiO2-Al2O3 和 Ru/SiO2-Al2O3 表现出最高的环己烷产率。 (C) 2011 Elsevier B.V. 保留所有权利。
Hydrodeoxygenation of the lignin monomer guaiacol was performed on the bifunctional catalysts of noble-metals supported on acidic matrices. The catalytic roles of metal nanoparticles and acidic supports were elucidated using the acid-site-measurement-dependent catalysis results, which demonstrated that metals were responsible for the hydrogenation of aromatic rings while metal-deposited acidic supports were indispensable to the deoxygenation of oxygenates. Among various combinations of metals and supports, Rh/SiO2-Al2O3 and Ru/SiO2-Al2O3 exhibited the highest cyclohexane yields. (C) 2011 Elsevier B.V. All rights reserved.
