Sol-gel Preparation of Photocatalytic Sm2Ti2O7/HZSM-5 Composite on Degradation of Reactive Brilliant Red X-3B

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...
