Tetrapyrrolic Macrocycles with Magnesium, Alluminum, and Zinc in Hydrogen Peroxide Decomposition

Activity of tetrapyrrolic macrocycles such as chlorins and phthalocyanines with magnesium, alluminum, and zinc in hydrogen peroxide decomposition in dark and under visible light irradiation was studied. Using adsorption isotherms the conditions for obtaining photocatalytic systems with varying degrees of adsorption of phthalocyanines were revealed. In adsorption systems, the activity of metal complexes depends on their molecular association. The principles allow to obtain the most effective photocatalysts were found.
