In this research, in situ hydrogenation of phenol to cyclohexanone and cyclohexanol in aqueous medium using sodium formate as a hydrogen source was studied by two catalysts, Pd@KIT-5 and Pd/Ni@CTF. Reaction temperature, time, catalyst types, the amount of initial phenol, and sodium formate, which are the most effective factors for phenol conversion to cyclohexanone and cyclohexanol, were investigated for both catalyst groups and the optimum values were reported. In the first study, the Pd10%@KIT-5/350 catalyst was selected as the most effective catalyst. The best results were obtained at a temperature of 40 °C and a reaction time of 6 hours, the amount of 0.1:0.05 g of phenol to catalyst ratio in 10 mL of deionized water with 0.5 g of sodium formate as the hydrogen source. Under these conditions, 99% phenol conversion was obtained. In the second study, Pd2%/Ni5%@CTF was selected as the optimal catalyst, and a 1:1 phenol to catalyst ratio exhibited excellent selectivity to form cyclohexanone at 110 °C for 6 hours with a conversion rate of 99%. Pd10%@KIT-5/350 and Pd2%/Ni5%@CTF catalysts were successfully recovered by centrifugation and filtration after use in the hydrogenation reaction of phenol and reused in four consecutive cycles. Pd2%/Ni5%@CTF showed better performance in reuse than Pd10%@KIT-5/350 catalyst. The results showed that the calcination temperature in the synthesis of Pd@KIT-5 catalysts has an important role in the hydrogenation reaction of phenol. The studies in this research showed that the higher the calcination temperature, the lower the percentage of phenol conversion, but the selectivity of the catalyst for the production of cyclohexanone increases.
