PURPOSE: A visible light active metal porphyrin-polyoxometallate hybrid material photo catalyst and the manufacturing method thereof are provided to show excellent thermal stability in the high temperature, and efficient generation of hydrogen by decomposing water with induced visible light. CONSTITUTION: A manufacturing method of visible light active metal porphyrin-polyoxometallate hybrid material photo catalyst comprises these following steps. Manufacturing the compound of chemical formula 2 by dissolving and reacting the porphyrin compound of chemical formula 1 with metal halide in the pyridine; Manufacturing the compound of chemical formula 3 by applying the compound of chemical formula 2 and potassium carbonate to the mixed solvents of tetra-hydro furan and water; Applying nitric acid solution and acetone to the compound of chemical formula 3 to be crystallized, thereby manufacturing the porphyrinic complex compound of chemical formula 4; Manufacturing metal porphyrin-polyoxometallate hybrid material by applying the porphyrinic complex compound of chemical 4 and the polyoxometallate compound to water In the chemical formula 1-4, M is a metal which is selected from the transition metal belonging to the group 3-12, and metal as well as semimetal belonging to the group of 13 -15. X is the halogen atom which is selected from the group of F, Cl, and Br and I. |
