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.

The characteristics of the Me-doped bismuth ferrites were investigated using various characterization instruments including SEM, TEM, FTIR and porosimeter indicating that the Me-doped BiFeO with nanosheet-like square orthorhombic structure was successfully obtained. The catalytic activity of various Me-doped BiFeO was compared and the results indicated that the Cu-doped BiFeO at 0.

View Article and Find Full Text PDFTitanium dioxide (TiO2) has been broadly used as a photocatalyst because it has good stability and performance for degradation of pollutants. On the other hand, its efficiency as photocatalyst is limited since it can only be excited under UV-light radiation and has a rapid electron-hole recombination that occurs during the photodegradation. There are many studies focusing on adjusting the synthesis methods, addition of dopants and modifying the TiO2 structure to enhance its photocatalytic performance.
