and TiO2 nanoparticles that improved charge transfer and suppressed electron–hole recombination. A further investigation on the role of the active species on Fe2O3/TiO2 confirmed that the crucial active species were both holesandsuperoxideradicals. The Fe2O3(0.5)/TiO2 sample also showed good
stability and reusability, suggesting its potential for water purification applications.

probably due to their low formation.
The scavenger study was also conducted using the Fe2O3(0.5)/TiO2 (PD) as shown in Figure 7. It was clear that the Fe2O3(0.5)/TiO2 (PD) gave similar trend of activity as the ones obtained on the unmodified TiO2 (NT). Both the photogenerated holesandsuperoxideradicals
