【 摘 要 】

Heterogeneous oxidation of cyclohexane with tertiobutyl hydroperoxide was carried out on Pt/oxide (Al₂O₃, TiO₂ and ZrO₂) catalysts in the presence of different solvents (acetic acid and acetonitrile). The catalysts were prepared using Pt(NH₃)₂(NO₂)₂ as a precursor and characterized by chemical analysis using the ICPâ€�?�AES method, XRD, TEM, FTIR and BET surface area determination. The oxidation reaction was carried out at 70°C under atmospheric pressure. The results showed the catalytic performance of Pt/Al₂O₃ as being very high in terms of turnover frequency.
