                         support in Pd electrocatalyst for ethanol oxidation reaction (EOR) 
                         in alkaline medium. Pd/aBC sample was compared with a commercial 
                         Vulcan carbon supported Pd electrocatalyst. The Pd particles 
                         morphology were influenced by the high content of oxygenated 
                         surface functional groups of aBC support, which can be relevant 
                         for the synthesis of Pd based electrocatalysts, because the Pd 
                         particles formation mechanism involves the adsorption of Pd2+ on 
                         negative charged sites of aBC support. This adsorption occurs 
                         preferentially on electron donor sites such as oxygenated 
                         functional groups. Therefore, the higher concentration of these 
                         groups in aBC surface can determine a higher concentration of 
                         initial nuclei sites for Pd particles formation contributing to 
                         the particles agglomeration on aBC support, compromising the 
                         Pd/aBC electrocatalytic performance. For both prepared 
                         electrocatalysts, the spectroelectrochemical analysis demonstrates 
                         that the acetate ion is the main product of the EOR in the 
                         alkaline medium.",
