The Surface Properties of LaAlO3 Perovskite Oxides and Their Catalytic Activities
Abstract:
A series of rare earth aluminate oxides were prepared by nitrate decomposition. The catalysts obtained were characterized by XRD, CO_2 TPD and XPS techniques and their catalytic activities for methane coupling were measured, The experimental results showed that the basicity of the surface can be interpreted by the double ioni-zation energy of oxygen species on the surface. There exists some correlation between this parameter and their catalytic activities.
