NaX zeolite was modified by platinum via impregnation/thermal decomposition
technique, using Pt(II)-acetylacetonate in acetone as an impregnating
solution. The samples were characterized by scanning electron microscopy
(SEM) and cyclic voltammetry methods. The mixture of modified zeolite and 10
wt % of carbon black, in a form of thin layer, was pasted to a glassy carbon
surface. With this mixture as the electrode material hydroxide ions oxidation
was studied by cyclic voltammetry. The response of modified zeolite
electrodes was compared with bare platinum electrode and platinum electrode
covered with Nafion film.
