| Abstract: | Nanostructured LaCo1-xZnxO3 (x=0,0.05,0.1,0.2,0.3 and 0.5) perovskites were synthesized by a one-step citric acid-complexing method for hydrogen production by the steam reforming of ethanol.For comparison,8% CoO/ZnO and 8% CoO/La2O3 were prepared by impregnation and evaluated.The catalyst samples were characterized by X-ray diffraction,temperature-programmed reduction,and X-ray photoelectron spectroscopy.The results indicated that zinc did not favor the formation of the LaCo1-xZnxO3 perovskite and the struc... |
