Abstract

Graphical abstract: Highlights: A direct catalytic conversion of cellulose to EG and 1, 2-PG was achieved on Pt/CNTs. Highly dispersed Pt/CNTs catalysts with particle size less than 5 nm were prepared. The total yields of up to 71.4% for EG and 1, 2-PG were obtained. A conversion pathway of cellulose to EG and 1, 2-PG was proposed. Abstract: A series of Pt nanoparticles supported on carbon nanotubes (CNTs) were synthesized using the incipient-wetness impregnation method. These catalysts were characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy, and transmission electron microscope (TEM) techniques. The characterization results indicate that the Pt nanoparticles were highly dispersed on the surface of the CNTs, and the mean size was less than 5 nm. These catalysts were utilized to convert cellulose to hexitol, ethylene glycerol (EG), and 1, 2-propylene glycol (1, 2-PG) under low H2 pressure. The total yields were as high as 71.4% for EG and 1, 2-PG using 1 Pt/CNTs as the catalyst in the hydrolytic hydrogenation of cellulose under mild reaction conditions.
