摘要：
Silica-pillared and non-pillared HNb3O8 samples were doped with nitrogen for rhodamine B photodegradation under visible light irradiation. The results indicate that silica pillaring could have significant impacts on the photocatalytic activity of the HNb3O8 sample. With expanded interlayer spacing and stronger adsorption ability to dye molecules, the SiO2 pillared and nitrogen-doped HNb3O8 sample performed much better than the non-pillared counterpart. The characteristics of samples were investigated by techniques such as XRD, FT-IR, UV-visible diffuse reflectance spectroscopy, SEM, and TEM. The relationships between catalyst structure and performance were discussed. (C) 2011 Elsevier B.V. All rights reserved.
