Structural and electronic effects boosting Ni-doped MO2C catalyst toward high-efficiency C—O/C—C bonds cleavage
文献摘要：
The selective cleavage of C—O and C—C is facing a challenge in the field of catalysis.In the present work,we studied the influence of doped Ni on the structure and electronic properties,as well as the selective C—O/C—C bond cleavages in the hydrodeoxygenation of palmitic acid over Ni-Mo2C catalyst.The catalytic activity on Ni doped Mo2C with TOF of 6.9×103 h-1 is much superior to intrinsic Mo2C catalyst,which is also higher than most noble metal catalysts.Structurally,the doped Ni raises the active particle disper-sion and the coordination numbers of Mo species(Mo-C and Mo-O),improves the graphitization degree to promote the electron transfer,and increases the amount of Lewis and Br?nsted acid,which are respon-sible for the excellent hydrodeoxygenation performance.The Ni promotes simultaneously C—O and C—C bonds cleavage to produce pentadecane and hexadecane owing to the increase of electron-rich Mo sites after Ni doping.These findings contribute to the understanding of the nature of Ni-doped Mo2C on the roles as catalytic active sites for C—O and C—C bonds cleavage.
