Rh₂O₃/hexagonal CePO₄ nanocatalysts for N₂O decomposition

Abstract

Hexagonal CePO₄ nanorods were prepared by a precipitation method and hexagonal CePO₄ nanowires were prepared by hydrothermal synthesis at 150 °C. Rh(NO₃)₃ was then used as a precursor for the impregnation of Rh₂O₃ onto these CePO₄ materials. The Rh₂O₃ supported on the CePO₄ nanowires was much more active for the catalytic decomposition of N₂O than the Rh₂O₃ supported on CePO₄ nanorods. The stability of both catalysts as a function of time on stream was studied and the influence of the co-feed (CO₂, O₂, H₂O or O₂/H₂O) on the N₂O decomposition was also investigated. The samples were characterized by N₂ adsorption-desorption, inductively coupled plasma optical emission spectroscopy, X-ray diffraction, transmission electron microscopy, X-ray photoelectron microscopy, hydrogen temperature-programmed reduction, oxygen temperature-programmed desorption, and CO₂ temperature-programmed desorption in order to correlate the physicochemical and catalytic properties.

Key words： Rh₂O₃; CePO₄; N₂O decomposition
