Abstract :3,4 and 2,5- dihydroxybenzene compounds were separately and covalently coupled to the multiwalled carbon nanotube insert ignore into journalissuearticles values(MWCNT); deposited on the surface of glassy carbon electrode through electrochemical reduction of diazonium compound of benzylamine bearing Boc protecting group insert ignore into journalissuearticles values(tert-butyloxycarbonyl);. Following the removal of the Boc group, an amide bond was formed between the amine-terminated surface and the acyl group of the dihydroxybenzene derivatives. The electrochemical properties of dihydroxybenzene-modified MWCNT and the influence of the sweep rate on the voltammogram were elucidated by cyclic voltammetry insert ignore into journalissuearticles values(CV);. Electron transfer kinetics of modified MWCNT by dihydroxybenzene derivatives was also studied using Laviron’s theory. As evidenced by an improvement in the anodic peak current and a negative shift in the overpotential of NADH oxidation when compared to the bare MWCNT, 3,4 and 2,5- dihydroxybenzene modified MWCNT electrodes were shown to possess catalytic activity toward NADH oxidation.
