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, the direct formic acid fuel cells (DFAFCs), in which the electrooxidation of formic acid (FA) represents the anodic reaction, have shown superiority over the traditional hydrogen and direct methanol fuel cells (DMFCs) in providing electricity for portable electronic devices. Nevertheless, DFAFCs experience a severe drawback where the catalytic activity of the Pt anodes ceases with time due to the adsorption of the poisoning CO intermediate resulting from the 2non-faradaic3 dissociation of FA. This ultimately deteriorates the overall performance of DFAFC. In this proposal, the catalytic activity and stability of several novel binary catalysts will be addressed towards FA oxidation
