CaSnO3粒子的合成、表征及对亚甲基蓝的光催化性能
Synthesis, Characterization of CaSnO3 Particles and Its Photodegradation Property for Methylene Blue
摘要
Abstract
Perovskite CaSnO3 particles were synthesized by a co-precipitation method.The formation and microstructure of the particles were characterized by XRD, TG-DSC, IR and SEM.The photocatalytic activity of particles on methylene blue was also investigated.The results indicated that there existed the crystal transformation in the reaction process.The reaction temperature had important influence on purity and crystallinity of products.It could be prepared pretty easily at 600 ℃.When the photocatalysts were irradiated by the visible light, the photo-degradation could reach 94% as the concentration of photocatalysts was 70 mg /L and the reaction time was 100 min.关键词
