| Abstract: | Metal complex comprising of copper (II) coordinated to nicotinamide and potassium thiocyanate ligands was synthesized and characterized. The metal complex was immobilized by anchoring on ammonium salt of phosphotungstate [(NH4)3(PW12O40)] and phosphomolybdate [(NH4)3(PMo12O40)] by hydrothermal method. Green procedure was followed during synthesis of organic-inorganic hybrids. The synthesized metal complex and organic-inorganic hybrids were characterized by elemental analysis, FT-IR., DR-UV-Vis, EDX, SEM and powder XRD. Powder XRD of organic-inorganic hybrids gave reflection at around 2θ=9, confirming the preservation of the Keggin structure. Since the Keggin structure was maintained after the immobilization of the complex, the immobilization strategy was successful. The metal complex as well as organic-inorganic hybrids were studied for their catalytic activity for oxidative conversion of alkyl aromatic, cyclocycloalkane and cycloalcohols. Gas chromatography (GC) and mass spectroscopy (MS) was used for the determination of products formed during catalysis. The heterogeneous catalysts showed high catalytic activity and good product selectivity. The catalysts were recycled and reused multiple times with no substantial loss of their catalytic activity. |
