Synthesis of Pd nanoparticles supported on CeO2 nanotubes for CO oxidation at low temperatures
چکیده انگلیسی

Developing efficient supported Pd catalysts and understanding their catalytic mechanism in CO oxidation are challenging research topics in recent years. This paper describes the synthesis of Pd nanoparticles supported on CeO2 nanotubes via an alcohol reduction method. The effect of the support morphology on the catalytic reaction was explored. Subsequently, the performance of the prepared catalysts was investigated toward CO oxidation reaction and characterized by Nitrogen sorption, X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, and CO-temperature-programmed desorption techniques. The results indicated that the catalyst of Pd on CeO2 nanotubes exhibits excellent activity in CO oxidation at low temperatures, due to its large surface area, the high dispersion of Pd species, the mesoporous and tubular structure of the CeO2-nanotube support, the abundant Ce3+, formation of Pd–O–Ce bonding, and enhanced metal–support interaction on the catalyst surface.

The preparation of CeO2 nanotube-supported Pd nanoparticles and their catalytic performance toward CO oxidation were described. Abundant Ce3+ and Pd–O–Ce interactions on the nanotube facilitated the reaction.Figure optionsDownload as PowerPoint slide
