                         Cu/Sn alloy nanoparticles on Boron Doped Diamond (BDD) films in 
                         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 
                         electrocatalytic reduction of nitrate in 0.1 M Britton-Robinson 
                         (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.",
