Photoelectrocatalytic degradation of humic acid with CdS/TiO2 nanotubes electrode.
Highly ordered TiO2 nanotubes were synthesized using electrochemical anodization method and then were modified by semiconductor CdS particles to construct CdS/TiO2 electrode. The synthesized CdS/TiO2 nanotubes were used for the experimental study of influences of PH and added electronic voltage on humic acid degradation through photoelectrocatalysis. The results indicated that the highest degradation rate of 92% was obtained when the pH was 8 and the voltage was 15 V. The electrodes can still maintain high catalytic activity after repeated use.
