磷掺杂二氧化钛制备光催化剂降解亚甲基蓝研究

通过溶胶凝胶法来制备磷掺杂二氧化钛,利用XRD技术对样品进行表征,探讨对亚甲基蓝(MB)的催化降解性能。结果表明,P-TiO_2的光催化降解MB效果更好,P-TiO_2制备最佳工艺为P/Ti=0.05,焙烧温度550℃,光催化剂的最佳用量为0.06mg/L,MB初始浓度10mg/L,溶液偏中性条件下时,更有利于P-TiO_2光催化降解。

This experiment generate P-TiO2by sol-gel method.The ynthesized samples were characterized byX-ray diffraction,the catalytic egradation properties of methylene blue(MB)are discussed.The results show thatthe P-TiO2photocatalytic d egradation of MB is better than TiO2.The best P-TiO2preparation process for P/Ti=0.05,calcination temperature50℃,the best dosage of photocatalyst is0.06mg/L,initial concentration of MBis10mg/L,MB solution under the condition of partial neutral,is more advantageous to P-TiO2photocatalyticdegradation.
