摘要
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 oxide（MnO2）/2,2＇-bipyridine iron Fe（bipy） 32＋ composite was synthesized by an electrostatic adsorption layer-by-layer self-assembly technique, and characterized by scanning electron microscopy（SEM）, ultraviolet-visible（UV-Vis） spectra and electrochemical measurements.The results showed that Fe（bipy） 32＋ was uniformly deposited by the layer-by-layer adsorption technique and the photocurrent of self-assembled film was increased under visible light irradiation.This system could degrade 57% of RhB（with concentration of 1×10-5 mol/L） in 80 min, which could achieve a better effect of degradation in short time.
