abstract = "Copper nanoparticle electrodeposition and consolidation processes
were studied on boron doped diamond (BDD) electrode submitted to
hydrogen and oxygen plasma treatments. The modified BDD films were
applied as electrodes for nitrate electroreduction. The results
showed that both treatments have a strong influence on the copper
deposition and dissolution processes. For BDD treated with
hydrogen plasma the copper electrodeposit was homogeneous with
high particle density. This behavior was attributed to the BDD
surface hydrogenation that improved its conductivity. On the other
hand, the treatment with oxygen plasma was important for the
copper nanoparticle consolidation on BDD surface, confirmed by the
result's reproducibility for nitrate reduction. This performance
may be associated with the formation of oxygen groups that can act
as anchor points for Cu-clusters, enhancing the interfacial
adhesion between diamond and the metal coating. The best
electrochemical nitrate reduction response was obtained in acid
media, where occurred the separation of the nitrate reduction
process and the water reduction reaction.",
