Fuel cell in this study consumes methanol as fuel and they are very important for clean environment and effective energy conversion. Graphitic carbon nitride (g-C3N4) is carbon allotrope among carbon based nanomaterials. It consists of C-N bonds in p-based polymer. Polyoxometalates (POMs) are redox-active materials and have crucial potential for direct methanol oxidation and energy storage. POMs attract important interest because they included in high-valent metals and anionic metal oxides. In present report, the nanocomposite of polyoxometalate/C3N4 NTs was synthesized and applied for fuel cell. Firstly, the structure of prepared nanocomposite was investigated by transmission electron microscope (TEM), x-ray photo electron spectroscopy (XPS) and scanning electron microscope (SEM). After that, the voltammetric measurements were performed by using nanocomposite modified electrode. The electrochemical active areas of POM-C3N4 NTs/GCE and C3N4 NTs/GCE are 0.511 cm(2) and 0.169 cm(2), respectively. The prepared nanocomposite demonstrated active catalytic effect towards methanol.
