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 (1×10－5 mol/L)反应80 min降解率达到了57%.

The layered manganese oxide (MnO2)/2,2-bipyridine iron [Fe(bipy)] 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) 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.

Key words: layered manganese oxide, 2,2-bipyriding iron, photoelectrocatalysis, self-assembled film, rhodamine B
