Abstract
Selective cleavage of C–O bond in biomass-derived furfuryl alcohol (FFA), with complex chemical functional groups, poses a great challenge to biomass upgrading. In this work, Pt/Mg2AlO catalysts were prepared by urea hydrolysis (Pt-HT), coprecipitation (Pt-CP) and sol-gel (Pt-SG) methods to study the interfacial property caused by support synthesis methods during selective hydrogenation of FFA to 1,2-pentanediol (1,2-PeD). The results clearly showed that 1,2-PeD yield on Pt-HT was 60.3 %, better than those on Pt-CP and Pt-SG catalysts. The superior catalytic activity of Pt-HT is ascribed to effective adsorption and split of C–O bonds, facilitated by plentiful interfacial oxygen vacancies and Pt0 species. Furthermore, the superior selectivity of 1,2-PeD is related to the deforming non-parallel adsorption mode of FFA rings on Pt-HT resulting from their interaction with interfacial oxygen vacancies.
期刊介绍：
Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues.
Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
