运用循环伏安法研究了不同条件下锰离子在金属钛基底上的电化学行为,结合X射线衍射仪(XRD)和扫描电镜(SEM)对电解产物表征,探讨了温度、电压、硫酸浓度对电解产物的组分、形貌和颗粒尺寸的影响,结果表明硫酸浓度较温度对电沉积二氧化锰氧化电流起峰电位的影响更为显著,改变反应条件可控制纳米MnO2晶体结构、形貌和颗粒大小。
Cyclic voltammetry was used to study the electrochemical behavior of manganese ions on metallic titanium substrates under different conditions. The characteristics of the electrolytes were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effects of temperature, voltage and concentration of sulfuric acid The results showed that the effect of sulfuric acid concentration on the peak potential of the electrodeposited manganese dioxide oxidation current was more significant than that of the temperature. The crystal structure, morphology and morphology of the nanometer MnO2 could be controlled by changing the reaction conditions the size of granule.
