基于烟道气脱除SO2光响应性MOF@GO复合纳米填充剂镶嵌的膜传递通道构建与脱硫性能研究

The emission of SO2 in flue gas is the important source of PM2.5. Based on the bionic ideas, transport channels construction and desulfurization performance investigation of light responsive metal organic framework@graphene oxide (LRMOF@GO) composite nanofillers embedded membrane are carried out to apply to the removal of SO2 in flue gas, inspired by the cell membrane structure and transport mechanism. Molecular simulation aided design will be adopted, and light responsive MOF@GO composite nanofillers will be designed and prepared. The relationship between the pore structure and the light responsive characteristics of light responsive MOF will be studied, optimizing of SO2 diffusion and permeability. The open metal sites and base sites in light responsive MOF will be investigated to optimizing of SO2 separation performance. Light responsive efficient SO2 transport channels will be constructed through the field induced directional arrangement or biomimetic mineralization method, within the membrane controllable embeded light responsive MOF@GO. The rule between the hybrid membrane structure and the construction of SO2 facilitated transport channels will be investigated, to realize the synergy of the solubility mechanism, diffusion mechanism and reactivity mechanism, strengthening SO2 separation process of the hybrid membrane.
