Production of hydrogen in a ternary photocatalytic system based on water-soluble palladium(II) porphyrin

Production of hydrogen in a ternary photocatalytic system based on water-soluble palladium(II)... A new photocatalyst, water-soluble palladium(II) complex with meso-tetrakis(4-N,N,N-trimethylammoniophenyl) porphyrin, was suggested as a component of a photocatalytic system for water reduction to hydrogen. In the ternary system palladium(II) porphyrin-methyl viologen-triethanolamine, the metalloporphyrin phosphorescence is quenched only by methyl viologen by the mechanism of oxidative electron transfer. The reduced form of methyl viologen is accumulated in the solution, and hydrogen is evolved in the presence of colloidal platinum. The highest quantum yield of the formation of the reduced methyl viologen form and hydrogen in the system reaches 0.4. After 1-h irradiation of the system, 125 mol of hydrogen is evolved per mole of metalloporphyrin. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
