Multicomponent Co-Zr-P-W-O immobilized zeolites toward solvent-free oxidation of toluene to benzaldehyde

A composite catalyst was prepared by impregnation of ZSM-5 in mixture solution of Co(NO3)2, ZrOCl2 and phosphotungstic acid (PW) and characterized by XRD, FT-IR, UV?vis, XPS, SEM and TEM techniques to confirm its structure and composition. The pre-prepared composite is composed of Co2(PO4)Cl, ZrO2, P2O5 and WO3 crystalline nanoparticles uniformly dispersed on ZSM-5 zeolite. The prepared composite demonstrates effective catalytic function for solvent-free oxidation of toluene into benzaldehyde with H2O2 oxidant, achieving 16.6% conversion and 90% selectivity. The effect of various components composed of the catalyst and reaction conditions on the catalytic function were explored. Moreover, the recovery and reusability of the catalyst were estimated, presenting good reusability.
