                         order to improve their electrocatalytic activity and selectivity 
                         for application in nitrate electrochemical reduction. Cyclic 
                         voltammetry measurements evidenced the formation of Cu/Sn alloy 
                         electrodeposited on BDD electrode. The electrodeposited Cu/Sn can 
                         be better visualized by analyzing the dissolution process. By 
                         studying the dissolution peak separately, the dissolution peak of 
                         the Sn was obtained at a more positive potential, when compared 
                         with the dissolution peak of Cu. From the scanning electronic 
                         microscopy (SEM) analysis, the homogeneous distribution of the 
                         Cu/Sn alloys particles on BDD surface with grain size in 
                         nanometric scale was verified. From X-ray diffraction analysis, 
                         two Cu/Sn alloy phases (Cu41Sn11 and Cu10Sn3) were identified for 
                         the electrodeposits obtained at -0.5V and charge of 0.26 C. The

                         (BR) buffer solution with pH 9 was analyzed. The BDD electrode 
                         modified with Cu/Sn alloy nanoparticles proved to potentiate the 
                         electrocatalytic reduction of nitrate.",
