Abstract Phenolic substances are harmful to humans and other living things, even at low concentrations. Therefore, phenol must be removed from water with the proper process. One of the most effective processes for degrading phenol is heterogeneous catalytic oxidation. Three carbon materials as supports were used to prepare manganese-oxide based catalyst (2.5% MnOx/ACP and 2.5% MnOx/ACN), and graphene oxide (2.5% MnOx/GO). These catalysts were tested for the degradation of phenol in aqueous solution using peroxymonosulfate as a source of sulfate radical. The physio-chemical catalysts were characterised by several characterisation techniques such as powder X-ray diffraction, N2-sorption (BET), scanning electron microscopy (SEM) equipped with Dispersive Energy X-ray Spectroscopy (EDS). In comparison to other catalysts, heterogeneous activation of peroxymonosulfate was more effectively done by 2.5% MnOx/ACP, resulting in a higher production rate of sulfate radicals. In the presence of a catalyst at 0.2 g and 1 g peroxymonosulfate in 500 mL solution at 25 °C, 90% total organic carbon (TOC) removal and phenol decomposition of 100% was achieved in 90 min with phenol concentration of 75 mg/L. First-order kinetics were followed by phenol decomposition with the energy of activation on 2.5% MnOx/ACP of 15.0 kJ/mol.

碳负载锰用于过硫酸盐的异相活化，以分解水溶液中的苯酚

摘要 酚类物质即使在低浓度下也对人类和其他生物有害。因此，必须通过适当的工艺从水中去除苯酚。降解苯酚的最有效方法之一是多相催化氧化。三种碳材料作为载体用于制备氧化锰基催化剂（2.5% MnOx/ACP 和 2.5% MnOx/ACN）和氧化石墨烯（2.5% MnOx/GO）。使用过氧单硫酸盐作为硫酸根的来源，测试了这些催化剂在水溶液中降解苯酚的能力。物理化学催化剂通过多种表征技术进行表征，例如粉末 X 射线衍射、氮气吸附 (BET)、配备色散能 X 射线光谱 (EDS) 的扫描电子显微镜 (SEM)。与其他催化剂相比，2.5% MnOx/ACP 可以更有效地完成过氧单硫酸盐的多相活化，从而提高硫酸根自由基的产生率。在 0.2 g 和 1 g 过氧化单硫酸盐的催化剂存在下，在 25 °C 的 500 mL 溶液中，在 90 分钟内实现了 90% 的总有机碳 (TOC) 去除和 100% 的苯酚分解，苯酚浓度为 75 mg/L . 一级动力学之后是苯酚分解，在 2.5% MnOx/ACP 上的活化能为 15.0 kJ/mol。
