dc.description.abstract The electron transfer and electrocatalytic proiperties of iron oxide nanoparticle (g-Fe2O3) catalysts supported on MWCNTs are described. The MWCNT-Fe2O3 and its electrodes were successfully characterised with FESEM, HRTEM, XRD, EDX, cyclic voltammetry and electrochemical impedance spectroscopy. The MWCNT-Fe2O3 based electrodes demonstrated fastest electron transport and current response towards DA compared to other electrodes studied, giving a catalytic rate constant of 16.4 x 105 cm3mol-1s-1, sensitivity of 0.026 AM-1 and limit of detection of 3.3 x 10-7 M. The electrode may be potentially useful for the detection of DA in real drug sample analysis. en_US
