Potential of low-cost TiO-PVC composite in photoelectrocatalytic degradation of reactive orange 16 under visible light.

In recent years, previously reported studies revealed a high efficiency of pollutant degradation by coupling photocatalysis and electrochemical processes (PECs) using titanium dioxide (TiO) photoelectrode rather than using photocatalysis or electrocatalysis alone. However, some of the TiO photoelectrodes that have been reported were not cost-effective. This is due to the use of expensive chemicals and certain expensive equipment in the fabrication process, other than involving complicated preparation steps.
