Catalytic Performances of Au–Pt Nanoparticles on Phosphorous Functionalized Carbon Nanofibers towards HMF Oxidation

摘要: Herein, we reported the utilization of pre-formed Au–Pt nanoparticles deposited on phosphorus functionalized carbons as effective catalysts for oxidation 5-hydroxymethylfurfural (HMF) to furandicarboxylic acid (FDCA). have been prepared by a two-step methodology using polyvinyl alcohol (PVA) protective agent and combination NaBH4 H2 reducing agents. Three carbon nanofibers (CNFs) with different graphitization degrees through treatment an H3PO4–HNO3 mixture at 150 °C, in order incorporate P groups surface. Surface structural properties synthesized materials investigated transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy. The surface determine amount P-functionalities, which is key parameter affecting catalytic performances Au–Pt. Indeed, highest activity stability has achieved sample, showed largest P-groups
