This paper reports the preparation and electrochemical study of new glassy carbon electrode (GCE) bulk-modified with synthesized hybrid mat­erials: Pt and MoO2 nanoparticles deposited on the multi-walled carbon nano­tubes (MWCNTs). The results of electrochemical study of commercial GCE and electrodes modified with Pt–MWCNT and MoO2–MWCNT were obtained by cyclic voltammetry in K4Fe(CN)6 and NaOH solutions. Morpho­logy and structure of the synthesized hybrid materials were analysed using the method of high resolution transmission electron microscopy, indi­ca­t­ing the presence of well dispersed nanoparticles of Pt and MoO2 over MWCNT net­work. The results of the electrochemical study show that the capa­ci­tance of electrode modified with MoO2–MWCNT and Pt–MWCNT is 62–65 times higher than the capacitance of the commercial GCE.
