Efficient and Durable Photochemical CO2 Reduction by TiO2‐Immobilized Metal Porphyrin Catalysts

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
A dye‐sensitized TiO2 scaffold bearing IrP and 3d‐metalloporphyrin catalysts (M‐TCPP; M = Fe, Co, Ni, Cu) drives efficient CO2‐to‐CO conversion and H2 evolution. Robust TiO2 immobilization and rapid interfacial electron transfer within the ternary architecture underpin the markedly enhanced activities relative to the mixed homogeneous systems.

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias

Metabolites, 2014
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias.
