One-pot solvothermal preparation of mesoporous Cu(II)Porphyrin-TiO₂ composites with enhanced photocatalytic activity and stability

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

“…meso-(Hydroxyphenyl)porphyrins and their derivatives are frequently used to sensitize TiO 2 and the resulting materials typically show high photocatalytic activity. [110][111][112][113][114][115][116][117] For instance, Mu and co-workers 110 used porphyrins H 2 47, Zn47 and Sn47Cl 2 (Fig. 14) to sensitize TiO 2 nanoparticles in order to improve the photocatalytic activity of bare TiO 2 nanoparticles.…”

“…16) are efficient photocatalysts for the degradation of 4-NP (Table 8), but the highest efficiency was observed for Cu54-TiO 2 . 116,117 The chemical interaction between the carboxy groups of Cu54 and TiO 2 is stronger than the physical interaction of the ester groups of Cu53 with TiO 2 . 116 As the interaction strength increases, the electron transfer efficiency also increases, leading to a better photocatalytic effect.…”

A Pyridinium‐Pyridinium Zinc(II) Porphyrin Ion Porous Organic Polymer as Efficient Heterogeneous Catalyst for Cycloaddition of Epoxides with CO2

“…[6][7][8][9][10] Metalloporphyrins show excellent catalytic performance in many fields, such as catalytic oxidation/reduction, [11,12] and photocatalysis. [13,14] In particular, the CO 2 cycloaddition reaction catalyzed by metalloporphyrins has attracted growing attention. [15] Numerous monofunctional or bifunctional catalytic systems have been developed for the cycloaddition of CO 2 with epoxides.…”

A series of bifunctional metalloporphyrins as efficient catalysts for cycloaddition of CO2 with epoxides

“…Synchronously, research demonstrated that an efficient catalyst system for this cycloaddition reaction usually needs to contain two active sites, Lewis acid and nucleophile 23 . Especially, metalloporphyrins that have been proved to be useful for photocatalytic degradation of organic pollutants, 24 electrocatalysis of redox reaction in batteries 25–27 and oxidation of olefins 28 also show relatively high catalytic activity for cycloaddition of CO 2 with epoxides owing to the presence of metal centers as Lewis acid active sites and the stability, high efficiency, easy to modify and other excellent characteristics of the porphyrin molecules 29,30 . Meanwhile, manganese, magnesium, zinc, cobalt, nickel, aluminum, and other metals have been applied successfully to the cycloaddition of various epoxides and CO 2 31–37 .…”
