Recently, Prof. Wang Yanqin of the School of Chemistry and Molecular Engineering has made important research progress in the efficient catalytic conversion of biomass to biomass energy. The latest research results “Pd/NbOPO4 Multifunctional Catalyst for the Direct Production of Liquid Alkanes from Aldol Adducts of Furans†was published. In the German Journal of Applied Chemistry (Angew. Chem. Int. Ed. 2014, http://dx.doi.org/10.1002/anie.201403440). This work was completed by doctoral students Xia Qineng and Qian Qian under the joint guidance of Prof. Wang Yanqin and Prof. Xue Xueqing. The research was funded by the “973†project led by Professor Lu Guanzhong and the National Natural Science Foundation of China. The catalytic conversion of biomass to liquid alkane is usually performed in multiple steps. Under high temperature and high pressure, it will lead to the breakage of CC bonds, produce low values ​​of methane and CO2, and reduce the yield of liquid alkane, which in turn will lead to the deactivation of the catalyst. . This achievement innovatively constructed a multifunctional Pd/NbOPO4 catalyst, enabling the catalytic conversion of furan derivatives (derived from biomass) directly to liquid alkanes under mild conditions with a high yield of liquid paraffins (90%). Long catalyst life (250 hours). In this multi-functional Pd/NbOPO4 catalyst, NbOx plays a decisive role. It not only acts as an acid center for dehydration, but also acts as a strong oxophilic species with the function of breaking off the CO bond, making the reaction proceed under mild conditions. This is the first time that experimental and theoretical studies have been performed on the effect of NbOx on CO bonds. This achievement is of great significance for understanding the nature and role of Nb materials, and for the catalytic dehydrogenation and hydrogenation of biomass and its derivatives to biogasoline, bioaerosol and biodiesel. Prof. Wang Yanqin has been engaged in the research of “porous materials and catalysis†for more than 100 years. He has published more than 100 SCI papers, he cited more than 2,500 times, and H factor 26. In recent years, he has worked on the efficient catalytic conversion of biomass to synthesize energy and fine chemicals. A series of research results have been obtained and relevant results have been published one after another in Chem. Commun. 2011, 47:3924; ChemSusChem 2011, 4:1758; Green Chem.
