“…11 Moreover, total degradation of ethanol, step 5, needs high overvoltage anode material, and is seldom reported for type II anodes. [8][9][10][11] Nevertheless, evidence of a mixed situation with competition between steps 2 and 4 were found for Ni-P/SnO 2 /Ti 16 and Pt-Ru electrodes. 7,13 The introduction of SnO 2 shows the activation of the ruthenium active sites as observed for the voltammetric parameters (i/q*;q f,N ) but, it is not sufficient for the reaction to proceed toward CO 2 formation.…”
