The water-gas shift reaction (WGSR) has been carried out over CuO/Fe2O3 catalysts modified by different loadings of Al2O3 (0%-15% (w)), prepared by a stepwise co-precipitation method. Composite mixture CuFe2O4 was produced, and the crystalline size, redox property, and surface metallic Cu dispersion were manipulated. The appropriate introduction of Al2O3 can promote the phase transition of spinel CuFe2O4 from tetra nal to cubic, inhibit aggregation of Cu-crystallite, improve Cu dispersion, and increase the amount of weak basic sites, as confirmed using powder X-ray diffraction (XRD), Raman spectroscopy, N2 physisorption, N2O decomposition, and temperature-programmed desorption of carbon dioxide (CO2-TPD) techniques. In addition, a temperature-programmed reduction of hydrogen (H2-TPR) technique was used to investigate the reducibility of the modified CuO/Fe2O3 catalysts. It was found that the Al2O3-doping plays an important role in increasing the hydrogen consumption of the copper species, and decreasing reduction temperature. This means that the Al2O3 can promote a synergistic interaction between the copper and iron species in the CuO/Fe2O3 catalysts. Overall, the Al2O3-modified catalyst (10%(w)) has a smaller Cu particle size, better Cu dispersion, greater reducibility, and larger amount of weak basic sites, resulting in a much higher initial catalytic activity and better thermal stability.
