Morphology-controlled synthesis of 3D mesoporous rosette-like CeCoOx catalyst by pyrolysis of Ce[Co(CN)6] and applied for the catalytic combustion of toluene

Abstract

In this paper, 1D nanoparticle, 2D hexagonal nanosheet and 3D rosette-like Ce[Co(CN)6] were synthesized by hydrothermal process at different temperature, and CeCoOx catalysts with similar shapes were obtained by the pyrolysis of Ce[Co(CN)6]. T90 of 1D nanoparticle, 2D hexagonal nanosheet and 3D rosette-like CeCoOx catalysts were 306, 275 and 163 oC, respectively. The 3D order mesoporous rosette CeCoOx emerged superior catalytic activity of toluene combustion, and this catalyst possessed superior thermal stability and moisture resistance, and three consecutive catalytic runs curves possessed very well overlapping during to more oxygen vacancy, larger pore size, higher surface Ce3+ species, surface Co3+ species and surface chemical adsorbed oxygen.
