摘要： 制备了 Cu 修饰的 MnCeOx 催化剂, 并用于苯酚水溶液氧化降解反应. 结果表明, Cu 的加入可以显著提高 MnCeOx 催化剂上苯酚氧化深度和溶液化学耗氧量去除率. 通过 X 射线衍射和程序升温还原等手段对催化剂中 Cu 的作用进行了考察, 发现 Cu 加入后形成了 CuMn2O4 物相, 从而有利于提高催化剂的氧化活性.

Abstract: Cu-modified MnCeOx catalysts were prepared and applied to the oxidative degradation of aqueous phenol solutions. The modification by Cu increased phenol oxidation and chemical oxygen demand removal of aqueous phenol solutions. The promotion effects of Cu were analyzed by X-ray diffraction and temperature-programmed reduction. It was found that CuMn2O4 formed with the addition of Cu, which was favorable for the increase of catalytic activity.
