【摘要】：借助有機自組裝一步軟模板法制備了鐵納米負載的有序介孔碳復合材料(Fe-OMC),用TEM、XRD和電化學技術對復合材料的結(jié)構、形態(tài)、組成等進行了表征,利用電化學技術研究了目標分子NaNO_2在Fe-OMC修飾電極表面的電子轉(zhuǎn)移過程.界面電荷轉(zhuǎn)移、界面電催化相關電化學研究發(fā)現(xiàn),該復合材料修飾電極能夠有效降低NaNO_2的過電位,對NaNO_2表現(xiàn)出良好的電催化氧化性能,其速率常數(shù)為52.51L·mol~(-1)·s~(-1),約為裸電極的1000多倍,有望將其用于NaNO_2的電化學催化及分析傳感研究.
[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.
