Abstract EN
The photocatalytic activity on decomposition of Rhodamine B (RB) of titanate nanotubes (TNTs) synthesized by alkali hydrothermal treatment method was evaluated using a microwave/UV/photocatalyst hybrid system.
The effects of each element technique as well as the synergy effects on decomposition of organic material were investigated.
When TNTs were ion-exchanged with HCl, Na+ content was reduced from 8.36 wt% to 0.03 wt%, whereas the TNTs calcined at 723 K was phase-transformed into anatase structure.
The RB decomposition rate increased with TNTs dosage as well as with microwave intensity.
Effect of addition of auxiliary oxidants on photocatalytic decomposition of RB was also investigated.
When ozone was added, the decomposition rate increased with the amount of ozone added.
When H2O2 was used as the auxiliary oxidant, however, addition of H2O2 exceeding a threshold amount caused reduction of decomposition rate.
A synergy effect was observed when H2O2 addition was combined with microwave-assisted photocatalysis.
