Effect of electron structure on the catalytic activity of LaCoO3 perovskite towards toluene oxidation

摘要

LaCoO3 perovskites with different spin states of Co3+ were prepared by calcination at 600-1000 degrees C. LaCoO3 with electron filling in the e(g) orbital at 1 exhibited a moderate interaction between the surface oxygen, resulting in the best catalytic activity. This was verified by the O p-band center.
