In this thesis, a description of the progress and the results of the four different projects that have been defined to design and introduction of the heterogeneous catalysts has been studied. In the first project, V 2 O 5 @TiO 2 was used in the reaction of m -xylene oxidation in the gas phase conditions and the effect of the size and distribution of vanadium pentoxide particles in the titanium dioxide network on the catalyst reactivity was investigated. The second project describes the synthesis of vanadyl-5,10,15,20-tetrakis (4-methoxycarbonylphenyl) porphyrin which has been immobilized onto the SBA-15 channels. The synthetic heterogeneous catalyst was employed in oxidation of cyclohexane using hydrogen peroxide at ambient temperature which showed a high conversion about of 85%. The third project, examines the synthesis and identification of the vanadyl-bis(salicylaldiminato) which is incorporated onto the organosilica support, and it was applied in the oxidation of benzene using molecular oxygen as a green oxidant and phenol was achieved with yield of 13.1%. The fourth project demonstrates the synthesis of the Copper (II) phthalocyanine complex which was synthesized under microwave conditions. This catalyst was used for oxidation of benzene to phenol using hydrogen peroxide at ambient temperature, which resulted the phenol whit the yield of 13.9% and selectivity of 98.9%.
