Photocatalytic degradation of methyl orange mediated by a silica coated nanomagnet porphyrin hybrid

Applications of Fluorous Porphyrinoids: An Update†

“…investigated the functionalization of silica‐coated Fe 3 O 4 NPs with zinc phthalocyanines to serve as optical sensors for harmful anions (153). As with the previous studies (77,78), aminopropyl groups attached to the silica coating of the NP served as nucleophiles to substitute an asymmetric A3B‐type phthalocyanine. Only one isoindole of the phthalocyanine substrate included fluorine atoms for substitution, while the other three were functionalized with tosylamino groups that were previously demonstrated to enhance the sensitivity for certain anions.…”

“…However, the NP-immobilized systems were good for at least three catalytic cycles with minimal loss of efficiency, while the homogeneous catalysts could not be recovered at all after the first use. They also reported the photocatalytic activity of ZnTPPF 20 and the corresponding free-base compound, H 2 TPPF 20, anchored to the same nanomagnet supports (78). The decomposition of methyl orange dye using H 2 O 2 as an oxidizer was studied, and it was shown that the hybrid porphyrin magnetic catalytic system was a more efficient catalyst than the corresponding nonimmobilized porphyrins.…”

Porphyrin-containing materials for photodegradation of organic pollutants in wastewaters: a review

“…In 2021, Simões and co-workers 184 developed a silica coated nanomagnet porphyrin hybrid and compared the ability of the Zn 83 –nanomagnet hybrid (Fig. 32) as a photocatalyst for the degradation MO with that of non-immobilized porphyrins H 2 83 and Zn 83 .…”

Three Isomeric Zn(II)–Sn(IV)–Zn(II) Porphyrin-Triad-Based Supramolecular Nanoarchitectures for the Morphology-Dependent Photocatalytic Degradation of Methyl Orange

“…Every year, the textile industry discharges large quantities of MO into the aqueous ecosystem, resulting in nonpotable water. 45,46 Thus, we also studied the morphologydependent photocatalytic degradation of MO in aqueous solution by these photocatalysts. ) complexes were synthesized according to a previously reported procedure.…”

“…MO is a water-soluble aromatic azo dye (commonly used as a pH indicator) and is extensively used in several industries, including the textile, paper, printing, and food industries. Every year, the textile industry discharges large quantities of MO into the aqueous ecosystem, resulting in nonpotable water. , Thus, we also studied the morphology-dependent photocatalytic degradation of MO in aqueous solution by these photocatalysts.…”
