Metalloporphyrins have been regarded as one of the most promising electrocatalysts for oxygen reduction reactions (ORRs) due to their ease structure modification and robust coordinated M−N4 environment. However, electrocatalytic activity, selectivity stability metalloporphyrin-based composite catalysts are often reported be much poorer than those Pt-based materials, arousing researchers devote ...
Heterogenized metalloporphyrin catalysts for oxidation reactions are extensively explored to improve chemical production. In this work, manganese meso-tetraarylporphyrins were immobilized on hydrated mesoporous titanium dioxide (SBET = 705 m2 g−1) through carboxylate or phosphonate anchoring groups separated from the macrocycle by 2-arylimidazole linker fused across one of pyrrolic rings macroc...
The interaction between two unsupported Ag(III)porphyrins, which exist as a metalloporphyrin dimer has been studied. UV-visible spectrum shows only slight change in Soret band position indicative of Ag(III) formation. Optimized structure the complexes clearly revealed that metal-centered oxidation results short Ag-N (porphyrin) distance with large distortion porphyrin macrocycle. dispersion eff...
Coordination polymer particles have attracted a great deal of attention due to their characteristic properties and diverse applications in the fields of gas storage, catalysis, optics, sensing, electronics, photochemistry, and biology. Herein, we investigated shape transformation reactions of zinc 5, 10, 15, 20-tetra(4-pyridyl)-21 H, 23 H-porphine (ZnTPyP)-containing coordination polymer partic...
