                         prepare an activated hydrothermal carbon supported nickel 
                         electrocatalyst (Ni/aHC) for ethanol oxidation reaction (EOR) in 
                         alkaline medium. The cyclic voltammogram obtained for the Ni/aHC 
                         sample in a 1.0 mol L-1 NaOH solution shows an anodic and a 
                         cathodic peak. These redox couple reaction peaks can be related to 
                         the reversible formation of (NiO)OH. The catalytic activity of the 
                         Ni/aHC sample regarding the EOR is clearly evident from the cyclic 
                         voltammogram obtained in presence of ethanol, where a significant 
                         increase in the current density from 0.55 V vs. Hg/HgO is 
                         observed. This potential value, related with the onset potential 
                         (E-onset) of the EOR, is very close to the corresponding (NiO)OH 
                         formation potential, confirming that this species is directly 
                         involved in the EOR on the Ni/aHC electrocatalyst. The in-situ 
                         Attenuated Total Reflectance FTIR (in-situ ATR-FTIRS) spectra of 
                         this sample show two intense peaks related with acetate ion 
                         formation. Based on the ATR-FTIRS and electrochemical analyses, 
                         and in the literature information, a reaction pathway of the EOR 
                         on Ni/aHC in alkaline medium is proposed.",
