In recent years, visible light has been used to drive the degradation of organic dyes, because of its straightforward, mild, environmentally friendly, and sustainable process for water purification and remediation. Herein, the design of Nickel porphyrin-based conjugated microporous polymer NiTPP-CMP with naphthalene ring linkage. The pore parameters and micro-morphology of NiTPP-CMP were studied by N2 adsorption/desorption and scanning electron microscopy, respectively, with a specific surface area of 135 m2g-1. To evaluate the efficacy of NiTPP-CMP as a heterogeneous photocatalyst, its photocatalytic activity, recoverability, and stability were assessed by studying the degradation of RhB. The results showcased the potential of NiTPP-CMP in effectively removing organic pollutants from industrial wastewater.
The organic pollutants photodegradation is a highly efficient and environment-friendly approach for water treatment. Herein, two 3D imine-linked porphyrin-based porous organic polymers were synthesized via the reaction between porphyrin (tetraaminoporphyrin and copper tetraaminoporphyrin) and tri(4-formylbiphenyl) amine, named HTTP and CuTTP. Both of them exhibited high surface area, wide absorption range, and narrow bandgap. Interestingly, HTTP and CuTTP were used as photocatalysts for organic dye photodegradation. However, CuTTP was found to exhibit higher photocatalytic performance than HTTP, this indicates tuning the metal of porphyrin rings can affect the properties of porphyrin-based porous organic polymers.
