Photocatalytic activity of alumina supported meso-tetra(۳-pyridyl)porphyrin

In order to design a new heterogenous porphyrin photosensitizer, in the present study, mesotetrakis(۳-pyridyl)porphyrin was immobilized on alumina and its photocatalytic activity for theaerobic photooxidation of organic substrates was studied. It is noteworthy that due to theadvantages of heterogeneous catalysts over the homogeneous counterparts [۱,۲] including higherstability and ease of catalyst separation, the former is of great interest in improving theperformance of catalyst and photocatalysts [۳,۴]. Very rapid oxidation of ۱,۳-diphenylisobenzofuran as a specific quencher of singlet oxygen [۵] in the presence of the hybridcompound showed the involvement of singlet oxygen as the main reactive oxygen species.
