Two porphyrin-based polymeric frameworks, SnP-BTC and SnP-BTB, as visible light photocatalysts for wastewater remediation were prepared by the solvothermal reaction of trans-dihydroxo-[5,15,10,20-tetrakis(phenyl)porphyrinato]tin(IV) (SnP) with 1,3,5-benzenetricarboxylic acid (H3BTC) 1,3,5-tris(4-carboxyphenyl)benzene (H3BTB), respectively. The strong bond between carboxylic group H3BTC H3BTB axial hydroxyl moiety SnP leads to formation highly stable architectures. Incorporating onto surface changes conformational frameworks well produces rigid structural transformation that includes permanent porosity, good thermodynamic stability, interesting morphology, excellent photocatalytic degradation activity against AM dye TC antibiotic under irradiation. activities found be 95% SnP-BTB 87% within 80 min. Within 60 min exposure, 70% 60% SnP-BTC. enhanced catalytic photodegradation performances attributed synergistic effect groups. connectors strongly resist separation from during experiments. Therefore, high rate low catalyst loading make or more efficient than other reported catalysts. Thus, present investigations on hold great promise in tackling treatment dyeing wastewater.
