摘要: Ruthenium oxide nano-catalysts supported on mesoporous γ-Al2O3 have been prepared by co-precipitation method and tested for CO oxidation. The effect of polyethylene glycol (PEG) the properties catalyst was studied. Addition PEG surfactant acted as a stabilizer induced change in morphology ruthenium from spherical nanoparticles to one-dimensional nanorods. Total conversion measured function at 175 °C 200 with 1.0 wt.% loading PEG-stabilized un-stabilized catalysts, respectively. Conversion routinely increased temperature but each case, exhibited notably higher catalytic activity compared equivalent. It can be assumed that increase is due changes porosity, shape dispersion engendered use PEG.
