This study compared the electrochemical degradation of 2-nitrobenzaldehyde (2-NBA) on the bored-doped diamond (BDD) and SnO2 electrode. The effect of several parameters such as current density, electrolyte type, initial 2-NBA concentration and temperature, were investigation in terms of degradation. The 2-nitrobenzaldehyde demonstrated different behaviors upon operative parameters on these two electrodes. Compared to the degradation on BDD, it performed better on SnO2 in wide operating conditions, and was proved to be more cost-effective and more suitable for 2-NBA mineralization. The presence of NaCl promoted that the 2-NBA degradation on both electrodes, which decreased on SnO2 but significantly improved on the BDD electrode.
