Title: Three-dimensional MoO3 nanoflowers assembled with nanosheets for rhodamine B degradation under visible light

Abstract

Highlights: • The orthorhombic three-dimensional MoO{sub 3} nanoflowers were synthesized by the modified hydrothermal method. • Using different amount of HCl to transfer from the h-MoO{sub 3} to the α-MoO{sub 3} was well discussed. • Better pore sizes and surface areas of the three-dimensional MoO{sub 3} nanoflowers accelerate the photodegradation process of RhB. • The three-dimensional MoO{sub 3} nanoflowers showed the photocatalytic activity (91.57%). • This methodology should be useful for preparing other nanostructured catalysts. - Abstract: Three-dimensional hierarchical nanoflowers self-assembled with the orthorhombic molybdenum oxide (α-MoO{sub 3}) nanoflowers were synthesized by the modified hydrothermal method. The structure characterizations of the three-dimensional α-MoO{sub 3} nanoflowers were carried out by scanning electron microscope (SEM), Energy Disperse Spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption-desorption measurement. Moreover, the three-dimensional α-MoO{sub 3} nanoflowers as photocatalyst exhibited enhanced photocatalytic activity towards photodegradation of Rhodamine B (RhB) under xenon (Xe) lamp irradiation. The results of SEM, EDS, XRD and nitrogen adsorption-desorption measurement showed the three-dimensional α-MoO{sub 3} nanoflowers have a better morphology, pore size (7.99 nm) and surface areas (50.788 m{sup 2} g{sup −1}) than hexagonal MoO{sub 3} (h-MoO{sub 3}) nanosheets, photocatalytic activity studies confirmed that the three-dimensional α-MoO{sub 3} nanoflowers photocatalyst exhibits a highmore » visible-light-driven activity for photodegradation of RhB solution of 91.57% within 160 min under Xe lamp irradiation. A mechanism was also proposed for the degradation of RhB by three-dimensional α-MoO{sub 3} nanoflowers.« less
