采用静电吸附层-层自组装方法制备了层状二氧化锰/2,2’-联吡啶铁自组装膜材料,借助扫描电镜(SEM),紫外可见光谱(UV-Vis)和电化学工作站等测试手段对自组装膜的结构与性能进行了表征.结果表明,该自组装膜具有均匀的表面和紧密的层状结构,在可见光照射条件下该自组装膜电极的氧化还原电流明显增加了.层状二氧化锰/2,2’-联吡啶铁自组装膜电极,在可见光照射条件下光电降解有机染料罗丹明B(1×10-5mol/L)反应80min降解率达到了57%. The layered manganese dioxide / 2,2’-bipyridyl iron self-assembled monolayer material was prepared by electrostatic adsorption layer-layer self-assembly method. SEM, UV-Vis and electrochemical workstation The structure and properties of self-assembled monolayers were characterized by means of measurement.The results show that the self-assembled monolayer has a uniform surface and a compact layered structure, and the redox current of the self-assembled monolayer is obviously increased under visible light irradiation. Layered manganese dioxide / 2,2’-dipyridyl iron self-assembled monolayers, the photodegradation of rhodamine B (1 × 10-5mol / L) under visible light irradiation for 80min resulted in a degradation rate of 57%.
