Preparation of a Novel Gold Nanoparticles Directly Modified Glassy Carbon Electrode and Study on Its Electrocatalytic Activity
摘 要
在不使用交联剂的情况下,借助种子媒介纳米金属生长法将纳米金直接修饰到玻碳电极表面.试验发现纳米金粒子在电极表面覆盖率为5.4×10-10mol·cm-2.[Fe(CN)6]3-/[Fe(CN)6]4-氧化还原电子探针的试验证明,纳米金修饰玻碳电极表面的电子传递速率是使用交联剂制备电极的四倍.与裸玻碳电极相比,抗坏血酸在该电极表面的氧化峰电位负移150 mV,峰电流提高2.2 μA,同时与尿酸的氧化峰电位差达到186 mV,可用于抗坏血酸和尿酸的同时检测.

Abstract
A novel gold nanoparticles modified glassy carbon electrode (Au/GC) was fabricated by the seed mediated growth method,without using cross-linking agents.As proved by SEM,nanoparticles of gold were successfully combined on the surface of glassy carbon electrode,having the surface coverage of 5.4×10-10mol·cm-2.It was found by testing with the redox electronic probe of [Fe(CN)6]3-/[Fe(CN)6]4-,that the speed of electron trasferring on the surface of this Au/GC electrode was about 4 times higher than that on the surface of gold nanoparticle modified GCE prepared by using cross-linking agents.The oxidative peak potential of ascorbic acid at the surface of Au/GC electrode was shifted negatively by 150 mV,and the peak current was raised by 2.2 μA.Difference of oxidative peak potentials between ascorbic acid and uric acid was attained to a value of 186 mV,which was feasible for the simultaneous determination of ascorbic acid and uric acid.
