Chapter 11. Porphyrinoids in Association with Nanomaterials for Water Purification

The existence of porphyrinoids makes the world of supramolecular chemistry a bigger and better place. With unique properties and extraordinary stability, porphyrinoids have emerged as a class of smart molecules. This chapter focuses on chemical structural aspects of porphyrinoids, with a special focus on their rich physico- and electrochemical properties. Porphyrinoids (namely porphyrins, phthalocyanines, and chlorins), which in conjugation with metal nanoparticles exhibiting antimicrobial properties, will also be highlighted. In addition, various modifications and working mechanisms of porphyrinoids as photocatalytic agents, which help in decontamination and photocatalytic disinfection of wastewater, will be summarized.
