采用硬模板法制备了有序介孔氧化锰, 并用过氧化氢氧化诺氟沙星的降解率及其抗菌活性变化评价了其催化活性. 研究发现, 有序介孔锰氧化物表现出较高的催化活性; 低 pH 有利于提高其催化活性. 与单独过氧化氢氧化过程相比, 有序介孔锰氧化物的存在明显减弱了诺氟沙星的抗菌活性. 叔丁醇对催化体系的抑制作用表明有序介孔锰氧化物促进了过氧化氢分解生成羟基自由基. 通过对诺氟沙星在催化过程中的分解产物鉴定, 提出了可能的分解途径.
Mesoporous manganese oxide was prepared by hard template method and its catalytic activity was evaluated by the degradation rate of norfloxacin by hydrogen peroxide and its antibacterial activity.It was found that ordered mesoporous manganese oxide showed higher Of the catalytic activity; low pH is conducive to improve its catalytic activity compared with the process of hydrogen peroxide alone, the presence of ordered mesoporous manganese oxide significantly reduced the antibacterial activity of norfloxacin tert-Butanol on the catalytic system The inhibitory effect indicates that the ordered mesoporous manganese oxide promotes the decomposition of hydrogen peroxide to generate hydroxyl radicals, and the possible decomposition pathway is proposed through the identification of the decomposition products of norfloxacin during the catalytic process.
