In this work, we describe the morphological, electronic and catalytic properties of support TiO-CeO-ZrO, prepared by sol-gel method, which was impregnated with copper at 5 and 10% by weight, in order to obtain efficient catalysts in the catalytic wet air oxidation (CWAO) of 2-cp. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM-EDS), UV-Vis diffuse reflectance spectroscopy (DRS) and nitrogen physisorption by the Brunauer-Emmett-Teller (BET) method. The activity of the materials used in this study revealed that without the presence of Cu, the SCO is low and with a content of 10% this metal shows the best catalytic behaviour; conversely, a reaction mechanism is proposed that describes the complete oxidation of 2-cp in this case.
在这项工作中，我们描述了通过溶胶-凝胶法制备的支持 TiO-CeO-ZrO 的形态、电子和催化特性，该支持物用 5%和 10%重量的铜浸渍，以获得在 2-cp 的催化湿式空气氧化（CWAO）中有效的催化剂。催化剂通过 X 射线衍射（XRD）、扫描电子显微镜（SEM-EDS）、紫外可见漫反射光谱（DRS）和氮物理吸附法（BET）进行了表征。在这项研究中使用的材料的活性表明，在没有 Cu 的情况下，SCO 较低，而在含有 10%Cu 的情况下，该金属表现出最佳的催化性能；相反，提出了一个反应机制，描述了在这种情况下 2-cp 的完全氧化。
