抗坏血酸在α-环糊精掺杂纳米碳管涂层电极上的伏安行为
VOLTAMMETRIC BEHAVIOR OF ASCORBIC ACID AT α-CYCLODEXTRIN INCORPORATED CARBON NANOTUBES-COATED ELECTRODE
摘要
Abstract
α-Cyclodextrin incorporated carbon nanotubes-coated electrode was fabricated and was applied to the electrocatalytic oxidation of ascorbic acid, reducing the overpotential by about 280 mV with an obviously increased current response. Basically, we would firstly like to capitalize on the best properties of the two components of the system, such as the electronic and catalytic properties of carbon nanotubes and the molecular recognition ability of α-Cyclodextrin. Characteristics of a supermolecular inclusion complex between α-Cyclodextrin and ascorbic acid were examined. A differential pulse voltammetric technique for measurement of ascorbic acid over the range of 2.5×10-6 to 1.0×10-3 mol*dm-3 has been developed.关键词
