酞菁类复合催化剂制备及光催化降解四环素性能

采用浸渍法制备了酞菁类复合催化剂,并利用扫描电镜、X射线衍射及红外等对其进行表征。以四环素为底物,探究了降解条件对复合催化剂的光催化降解四环素性能的影响。结果表明,当溶液呈弱碱性,在光照开始时加入过氧化氢1.5 mmol·L~(-1),催化剂与四环素的物质的量比为0.008 5∶1和光照时间60 min的条件下,四环素降解率达99%。

Preparation and photocatalytic degradation performance of phthalocyanine composited catalyst for tetracycline

Phthalocyanine composited catalyst was prepared by dipping method and characterized by SEM,XRD and FT-IR.The effect of the degradation conditions on the photocatalytic performance of composited catalyst for tetracycline was investigated.The results showed that the tetracycline degradation efficiency was up to 99% when the solution was weakly basic,the amount of hydrogen peroxide was 1.5 mmol·L^-1 as the light beginning,the mole ratio of catalyst to tetracycline was 0.008 5∶1,and the light time was 60 min.
