Abstract

An electrochemical method for the application of molybdenum oxide on multiwalled carbon nanotubes as well as its procedure is adduced. The preparation of molybdenum oxide applied on multiwalled carbon nanotubes is proven by an X-ray phase analysis and by electron micrographs. The obtained nanocomposite was investigated as an electrode material for oxygen electrodes of low-temperature fuel elements working in alkaline electrolyte. The current-voltage characteristics of the oxygen electrodes made of these nanocomposites are given. It is shown that the obtained nanocomposites based on molybdenum oxide are highly competitive in electrochemical characteristics with the electrodes made of activated carbon supported with platinum.
