Electrocatalysis at nanostructured materials has been a subject of a continuously growing interest, particularly for fuel cells applications. In fact, research in fuel cells is intensively growing with the global desire to obtain efficient, incessant, and green energy sources. In this context, direct liquid fuel cell (DLFC) is a clean, efficient, easily-operated energy conversion technology that has attracted much attention in the recent research. This technology uses a liquid fuel in the anode side. This fuel may be organic, inorganic, or bioorganic. The organic fuels include methanol, ethanol, propanol, ethylene glycol, glycerol, formaldehyde, formic acid, etc. whereas the inorganic fuels include boron hydride, hydrazine, etc. Alternatively, the bioorganic fuels include glucose, ascorbic acid, etc. Pt is the most commonly used anodic catalysts for the fuel oxidation in organic DLFCs but, unfortunately, it is usually poisoned by the reaction products (CO or CO-like intermediates). This will cause a severe drawback in the catalytic activity and stability of the electrode
