摘要：

Layered HNbWO6 nanosheet aggregation (e-HNbWO6) has been assembled by HNbWO6 nanosheet via an exfoliation-restaking route. The as-prepared samples are characterized by means of powder x-ray diffraction, scanning electron microscope, high-resolution transmission electron microscopy, laser Raman spectroscopy, ultraviolet-vis diffuse reflectance spectroscopy, and N-2 adsorption-desorption isotherms. The photocatalytic performances of the as-prepared samples are evaluated by degradation of methylene blue (MB). The results revealed that e-HNbWO6 has a specific surface area of about 156.5 m(2) g(-1), and exhibits a relatively excellent photocatalytic performance for degradation of MB under UV light.
