Formic acid electrochemical oxidation was studied using an electrode formed by Pd electrodeposited on third generation TiO2 nanotubes (TiO2NTBs-Pd), see inset in Figure 1A, in an alkaline medium. The electrochemical response of TiO2NTBs-Pd electrode towards formic acid oxidation was better than those corresponding to Ti or TiO2 nanotubes, see Figure 1A. Figure 1 (B) shows the typical Pd voltammetric regarding both Pd oxide formation and its reduction. From CO adsorption, see Figure1B, the real area of Pd electrodeposited was measured.  The formic acid oxidation on the TiO2NTBs-Pd electrode is shown in 1D.
