Fabrication of Fe3O4@C core-shell particles and its application in UV-Fenton oxidize removal of VOCs

  • 摘要: 采用一步水热法制备核壳结构Fe3O4@C微米粒子,通过比表面积及孔径分析仪、X射线衍射仪、透射电子显微镜、傅里叶变换红外光谱仪等对粒子结构和形貌进行表征,并研究了粒子作为非均相催化剂在UV-Fenton氧化去除挥发性有机物(VOCs)中的作用机制.结果表明,核壳结构Fe3O4@C粒子由于包覆了孔隙状碳层而具有较强的吸附能力,可显著增加VOCs气体分子与Fenton试剂的接触几率,有助于提高VOCs的去除效率.通过计算反应速率常数及协同因子,证实在核壳结构Fe3O4@C粒子去除VOCs的过程中存在吸附-催化氧化协同作用.
