Selective Synthesis of Amines by Heterogeneous Co Catalysts via Borrowing Hydrogen Protocols.

Developed Co-MgO/TiO was applicable to C-N bond formation by direct amination of primary and secondary alcohols with NH via a borrowing hydrogen protocol. Selective synthesis of primary, secondary, and tertiary amines was achieved by controlling the reaction conditions. Asymmetric secondary amines can be synthesized by the coupling of alcohols and amines.

Well-dispersed nickel nanoparticles on the external and internal surfaces of SBA-15 for hydrocracking of pyrolyzed α-cellulose.

Catalysts comprising nickel supported on SBA-15 were prepared by wet impregnation and co-impregnation methods. Wet impregnation was performed by directly dispersing an Ni(NO)·6HO aqueous solution into SBA-15, whereas in co-impregnation, ethylene glycol (EG) was added to nickel nitrate aqueous solution prior to dispersion into SBA-15. After drying and calcination, NiO/SBA-15w and NiO/SBA-15c were produced.
