Abstract:

The water-soluble metalloporphyrin is one of the most promising classes of compounds to be used as redox mediators/catalysts. In recent years, there has been increasing interest in the heterogeneous catalysis of metalloporphyrin, owing to the catalyst support on inorganic material not only maintain beneficial properties of catalyst, but also improve their catalytic activity and selectivity^[1]. For that purpose, scientists begin to search proper support to immobilization metalloporphyrin catalysts. In general, silica, alumina, zeolite, and clay minerals were utilized as matrixes to immobilize the metalloporphyrin.
