Title
Synthesis of nitrogen-doped carbon coated TiO2 microspheres and its application as metal support in cinnamaldehyde hydrogenation
Abstract

•Nitrogen-doped carbon coated TiO2 microspheres were prepared.•The composites were employed as support to disperse the PtCo catalyst.•The catalyst was used in cinnamaldehyde hydrogenation reaction.•The conversion increased with an increase of CNx amount in the catalysts.

N-doped carbon coated TiO2 microspheres (CNx/TiO2) were synthesized by the carbonization of the polypyrrole (PPy) coating on the surface of TiO2 microspheres and used as support to disperse Pt and PtCo nanoparticles for investing the selective hydrogenation of cinnamaldehyde. The support and catalysts have been characterized in terms of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscope (TEM), scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS). The hydrogenation results showed the conversion increased with an increase of CNx amount until the CNx coated TiO2 microspheres completely.
