Abstract
Highly dispersed Pt nanoparticles were fabricated on the surface of S-grafted carbon nanofibers (Pt/S-CNFs) and used in selective oxidation of glycerol with molecular oxygen in a base-free aqueous solution. Characterizations disclosed that S-grafted CNFs are more favorable for the dispersion of Pt than that of crude CNFs and HNO3-pretreated CNFs. CNFs supported Pt catalysts are more selective toward the formation of glycerin acid, and the initial activity of surface Pt atoms in Pt/S-CNFs reached 750.7h−1 at 60°C in a base-free aqueous solution.
