Preparation of micro and nano porous electrode array by using partial inhibition method with chromat ion at platinum electrode surface

In this study, use of a method was determined for the surface smoothness identify by applying cyclic voltammetry (CV) and linear scanning voltammetry (LSV) methods commercially available micro-sized platinum electrode. The parameters needed for coating was optimized using the cyclic voltammetry method. Micro and nano porous platinum electrodes were produced by laser pulling method. Images of the produced electrodes were obtained. Commercially available and produced micro and nano electrodes about radius magnitudes were calculated with the help of the currents from the voltamograms taken in ferrocene environment. Commercial and micro and nano porous platinum electrodes were coated with chromate ion by cyclic voltammetry method. The potantial-currents of commercial, micro and nano electrode arrays were compared. Surface images of nanoelectrodes were obtained by scanning electron microscopy (SEM).
