“…Metallophthalocyanines (MtPc) have attracted considerable attention as oxidation catalysts because of tetra N -donor macrocyclic structural similarity to the naturally occurring metalloporphyrins, their chemical and thermal stability, and their rather cheap and easy preparation on a large scale [1][2][3][4][5][6], whereas they have the following problems: low solubility, high aggregation tendency, and difficulty in catalyst recovery and recycling [7,8]. Strategies of immobilizing MtPc on multifarious insoluble supports, such as zeolites, activated charcoal, and clays, have been introduced to prepare polymeric phthalocyanine catalysts, facilitate catalyst separation and recycling, and reduce effluent contamination [9][10][11][12][13].…”
