Abstract
The best catalytic capacity of Nd-doped Ti/SnO2-Sb2O5 electrodes was obtained by sol-gel preparation. Nd-doped Ti/SnO2-Sb2O5 coating was characterized using technique such as scanning electron microscopy (SEM), and X-ray diffraction (XRD). Nd-doped electrode fragments looks smaller, more compact and more uniform than undoped electrode through SEM. The crystal cell’s average diameter of Nd-doped electrodes was 3.48nm through XRD. BOD5/COD of Reactive Brilliant Red X-3B increased 200% under optimum conditions after 1h electrolysis. Instantaneous current efficiency (ICE) was 51.15 % in first 40 min, 35.73 % in first 60 min. In the first 40 minutes of electrolysis process, COD of Reactive Brilliant Red X-3B changes conformed to the pseudo first-order kinetic equation. Electrical Properties Tests showed that the oxygen evolution potential values of Nd-doped electrodes were higher than the undoped electrodes in various media.
