摘要
The performance of La2NiO4 perovskite catalysts,prepared using a citric acid complexation method,for the steam reforming of ethanol was studied.The catalysts were characterized by X-ray diffractometry(XRD),specific surface area measurements(BET),thermogravimetric analysis(TGA)and scanning electron microscopy(SEM).The experimental results show that the calcination temperature and the amount of citric acid(CA)have a significant influence on the characteristics of the catalysts and their catalytic activity.Among the catalysts tested,the La2NiO4 catalyst calcined at 700 ℃withn(La):n(Ni):n(CA)of 2:1:3 exhibits the best activity and excellent stability as well as very low coke formation.
