Abstract
NiO/gamma-Al2O3 catalysts were prepared by the impregnation and the sol-gel method. The sintering and loss of nickel, carbon deposition and 80 h life- test for POM reaction over the catalyst were investigated by a now-reactor and by XPS, TG, EXAFS and AAS analysis. The results indicated that the sol- gel method could enhance the ability to suppress carbon deposition and to r esist nickel sintering and loss over nickel-based catalysts.
