Ni2P催化剂加氢脱氧机理研究进展

介绍了Ni2P催化剂的结构特征、加氢脱氧（HDO）活性相及生物油中典型的含氧化合物，综述了具有代表性的典型含氧化合物呋喃类、酚类、醚类和酯类在Ni2P催化剂上的加氢脱氧机理方面的最新研究进展。HDO过程中含氧化合物在催化剂作用下发生C-O键断裂，O主要通过加氢-氢解以H2O的形式脱除，其脱氧产物较为复杂。生物油中富含呋喃类和酚类化合物，因需要苛刻的脱氧反应条件，他们的脱氧难度最大。今后，需进一步深入开展HDO理论研究，探究Ni2P催化剂催化活性的调控机制，制备出性能更加优异的HDO催化剂。

Advance in the Hydrodeoxygenation Mechanism on Ni 2 P Catalysts

The structure of Ni2P catalyst, the active phase of the hydrodeoxygenation (HDO) and typical O-containing compounds of bio-oil are introduced, and the recent progress in the HDO mechanism over Ni2P catalysts based on representative O-containing compounds such as furans, phenols, ethers and esters is reviewed. During HDO, C–O bonds of O-containing compounds are cleaved under the action of catalysts, then the oxygen is mainly removed by hydrogenation-hydrogenolysis in the form of H2O. This process produces more complicated products. Bio-oils are rich in furans and phenolic compounds and these compounds need harsh deoxidization reaction conditions, therefore their HDO are the most challenging. To prepare the catalysts with a more excellent HDO performance, the HDO theoretical research and regulatory mechanism for HDO activity of the Ni2P catalyst are worthy of further studied.
