Morphology-dependent photocatalytic performance of Bi4Ti3O12
Source abstract
Abstract
Abstract Photo-catalysts with three dimensional (3D) morphologies exhibit high photo-catalytic activities and received more attention because of their large surface area and more active sites. In this work, 3D-microspheres, flower-ball and weaving-like Bi4Ti3O12 particles were prepared through a facile hydrothermal route with the assistance of different surfactants, in which all of 3D structures were assembled by Bi4Ti3O12 nano-rods. The as-prepared 3D Bi4Ti3O12 samples were characterized through power X-ray diffraction (XRD), Fourier-transform infrared (FTIR), scanning electron microscope (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption techniques and UV–vis diffuse reflectance spectra (DRS) to identify their crystal structures, morphologies, surface structure and light absorption abilities. Furthermore, the photo-catalytic abilities of samples were evaluated through the degradation Rhodamine B (RhB) under the drive of visible light. Results indicated that flower-liked Bi4Ti3O12 not only displayed the best catalytic efficiency but also possessed the good reusability and stability.
