Effect of substituted-hydroxyl groups on porphyrin ring in the photodegradation of 4-Nitrophenol

Photodegradation of pollutants is gaining extensive attention from the point of view eco-friendly. TiO2 is believed to be one of the most active photocatalysts. However, critical drawbacks of TiO2 are the large band gap and low surface area. Immobilization of TiO2 on support is a good manner to overcome to these disadvantages. On the other hand, Photosensitized catalysis is the initiation of degradation or transformation reactions of molecules using a combination of light and photoactive materials as catalysts [1,2]. Photodegradation of 4-Nitro phenol was performed in the presence of H2O2 as oxidant reagent. However, H2O2 is an oxidative material and may be have some drawback [3,4]. Motivation above work, Here we wish to report synthesize of the heterogenized functional metalloporphyrin with various number of OH group and investigation of their catalytic activity in the photodegradation of 4-Nitrophenol
