Metal (Co, Ce, Ni, Fe, Zn, Mn and Cu) containing Diatomite (D), Zeolite (Z) and Carbon Xerogel (CX) catalysts were prepared, characterized (SEM-EDX, TEM, FTIR and XRD) and tested as new catalysts in Catalytic Wet Air Oxidation (CWAO) of phenol in aqueous solution. Maximum values of Chemical Oxygen Demand (COD) or Total Organic Carbon (TOC) efficiencies were obtained in the case of Fe-D, Cu-Z, and Co-CX catalysts. Reaction pathway and kinetics for CWAO of phenol revealed a pseudo first-order catalytic process and a k_cat between 0.0473 × 10⁻³ and 1.4183 × 10⁻³ L/min g. (Di)carboxylic acids, acetic and oxalic were identified as oxidation organic products.

制备了含硅藻土（D），沸石（Z）和碳干凝胶（CX）的金属（钴，铈，镍，铁，锌，锰和铜）催化剂，进行了表征（SEM-EDX，TEM，FTIR和XRD）并进行了测试作为水溶液中苯酚的催化湿式氧化（CWAO）的新型催化剂。在Fe-D，Cu-Z和Co-CX催化剂的情况下，获得了化学需氧量（COD）或总有机碳（TOC）效率的最大值。苯酚CWAO的反应途径和动力学显示拟一级反应过程和k _cat在0.0473×10 ^-3和1.4183×10 ^-3之间 升/分钟 （二）羧酸，乙酸和草酸被鉴定为氧化有机产物。
