Al(2)CoO(4)-PbCrO(4) and Al(2)CoO(4)-Pb(2)CrO(5) crystalline powders in different proportions were obtained by the polymeric precursor method. Differential scanning calorimetry (DSC) and thermogravimetry (TG) techniques ...

Co-doped alumina powders were synthesized by means of the polymeric precursor method to obtain ceramic pigments. The effect of different contents of Co2+ on phase transition gamma to alpha-Al2O3 and appearing of CoAl2O4 ...

Co-doped alumina powders were synthesized by means of the polymeric precursor method to obtain ceramic pigments. The effect of different contents of Co2+ on phase transition gamma to alpha-Al2O3 and appearing of CoAl2O4 ...

Mesoporous CoAl2O4 was prepared by a non-aqueous solution method using aluminum chloride, cobalt nitrate and urea, dissolved in ethyl alcohol. The solvent evaporation was made by applying microwave radiation at low power. ...

ZrO(2), gamma-Al(2)O(3) and ZrO(2)/gamma-Al(2)O(3)-supported copper catalysts have been prepared, each with three different copper loads (1, 2 and 5 wt%), by the impregnation method. The catalysts were characterized by ...

NO, NO2 and N2O nitrogen oxides, named NOx, strongly contribute to the air pollution and to minimize their emissions are used catalytic processes. The catalytic reduction of NO with CO has the advantage to simultaneously ...

The selective catalytic reduction (SCR) of NO by propane in excess oxygen-containing gas mixture was studied on Co/Al2O3 catalyst. The oxygen concentration is very important for the reaction. The NO conversion to N2 without ...

In this work, alumina-supported platinum catalysts promoted with cobalt were analyzed in the preferential CO oxidation (PROX) reaction. The addition of Co represents a significant catalytic improvement with regard to the ...
