【Abstract】 In the process of SO₂ poisoning of rare earth complex oxide catalysts, we find that SO₂ diffuses into the bulk phase of the catalysts, When we link these diffusion results with the reaction conditions and the character of catalysts, we find that this diffusion is related to the reaction temperature, the distance between adjacent lattice planes, and the metal-oxygen bond energy.更多还原
