Sol-gel Preparation of Photocatalytic Sm2Ti2O7/HZSM-5 Composite on Degradation of Reactive Brilliant Red X-3B
Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> was loaded on the surface of HZSM-5 zeolite through a sol-gel route. HZSM-5 particles were coated with a thick layer of Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> to form the composite. I...

| description | Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> was loaded on the surface of HZSM-5 zeolite through a sol-gel route. HZSM-5 particles were coated with a thick layer of Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> to form the composite. It was found that crystallization of pyrochlore phase Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> begins at 800 °C. Continuous enlargement in Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> crystallite size and cell volume are accompanied with the increase of calcination temperature. The bandgap energy of the samples calcined at temperature ranging from 600 to 1000 °C was found to be around 3.4 eV. BET specific surface area and pore volume of the materials continuously decreased with rising calcination temperature. The 70 % Sm<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub>/HZSM-5 calcined at 800 °C was found to have the greatest photocatalytic activity on RBR X-3B degradation.<p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.24.3.18853">http://dx.doi.org/10.5755/j01.ms.24.3.18853</a></p> |
