Abstract

The new modified electrodebased on Meldola Blue (MB) adsorbed onto carbon aerogel (CA) incorporated into chitosan matrix and deposited onto glassy carbon (GC) disc were used for NADH electrocatalytic oxidation. MB was immobilized by simple adsorption on mesoporous CA (MB-CA) and was immobilized on a GC disc using chitosan matrix. The morphological and structural characteristics of the new electrode material such as specific surface area, pore size distribution, pore volume, were obtained from N2 adsorption - desorption isotherms and TEM measurements. The basic electrochemistry of adsorbed MB onto CA and its ability to catalyze NADH electrooxidation have been investigated by cyclic voltammetry and rotating disc electrode performed in different experimental conditions (potential scan rate, rotation speed, applied potential, NADH concentration, MB coverage). The electrocatalytic parameters of the investigated MB-CA/GC modified electrodes were estimated.
