摘要

通过不同温度煅烧获得不同比表面积的α-Fe₂O₃纳米颗粒,将纳米α-Fe₂O₃与壳聚糖制成复合材料。利用滴涂法,将纳米α-Fe₂O₃/壳聚糖复合材料修饰在玻碳电极上,并通过循环伏安法研究纳米α-Fe₂O₃/壳聚糖/玻碳电极对铁氰化钾电化学性能的影响。结果表明:随着烧结温度从280℃提高到700℃时,α-Fe₂O₃纳米颗粒的比表面积由136.5m²/g变为2.1m²/g。纳米α-Fe₂O₃/壳聚糖/玻碳电极能显著提高铁氰化钾的电化学性能,与裸电极相比,氧化和还原电流均显著提高,其电化学催化性能与其纳米α-Fe₂O₃比表面积密切相关,比表面积越大峰电流就越强。在最佳实验条件下,浓度在510^-4～510^-3mol/L范围内,铁氰化钾的还原电流与浓度呈良好的线性关系,检出限为1.25×10^-5mol/L,该修饰电极重复性和稳定性较好。

Abstract

α-Fe₂O₃ nanoparticles with different surface areas were obtained by calcination at different temperatures and then were combined with chitosan to form a composite material.The α-Fe₂O₃ nanoparticles/chitosan composite was modified on a glassy carbon electrode by the drop coating method,and the effect of the α-Fe₂O₃ nanoparticles/chitosan/glassy carbon on the electrochemical performance of potassium ferricyanide was studied by cyclic voltammetry.The results showed that the surface area of α-Fe₂O₃ nanoparticles changed from 136.5m²/g to 2.1m²/g as the sintering temperature increased from 280℃ to 700℃.The α-Fe₂O₃ nanoparticles/chitosan/glassy carbon electrode could significantly improve the electrochemical performance of potassium ferricyanide.Compared with the bare electrode,the oxidation and reduction currents were significantly increased.Its electrochemical catalytic performance was closely related to its surface area of the α-Fe₂O₃ nanoparticles.The larger the specific surface area,the stronger the peak current.Under the optimal experimental conditions,in the range of concentration from 5×10^-4 to 5×10^-3mol/L,the reduction current of potassium ferricyanide had a good linear relationship with the concentration,with a detection limit of 1.25×10^-5mol/L,and the modified electrode had good repeatability and stability.
