【摘要】：借助有机自组装一步软模板法制备了铁纳米负载的有序介孔碳复合材料(Fe-OMC),用TEM、XRD和电化学技术对复合材料的结构、形态、组成等进行了表征,利用电化学技术研究了目标分子NaNO_2在Fe-OMC修饰电极表面的电子转移过程.界面电荷转移、界面电催化相关电化学研究发现,该复合材料修饰电极能够有效降低NaNO_2的过电位,对NaNO_2表现出良好的电催化氧化性能,其速率常数为52.51L·mol~(-1)·s~(-1),约为裸电极的1000多倍,有望将其用于NaNO_2的电化学催化及分析传感研究.
[Abstract]:The ordered mesoporous carbon composites (Fe-OMCs) supported on iron nanoparticles were prepared by organic self-assembly one-step soft template method. The structure, morphology and composition of the composites were characterized by TEM XRD and electrochemical techniques. The electron transfer process of target molecule NaNO_2 on the surface of Fe-OMC modified electrode was studied by electrochemical technique. The results of interfacial charge transfer and interfacial electrocatalytic correlation electrochemical study showed that the composite modified electrode could effectively reduce the overpotential of NaNO_2. The electrocatalytic oxidation of NaNO_2 shows good performance, its rate constant is 52.51L 路mol / mol ~ (-1)) 路sbl ~ (-1), which is about 1 000 times of bare electrode. It is expected to be used in the electrochemical catalysis and analytical sensing of NaNO_2.
