Synthesis and photocatalytic behavior of BiVO4 with decahedral structure
Source abstract
Abstract
Abstract Decahedral BiVO 4 was successfully synthesized with Tween-80 as a template by the microwave hydrothermal method. The effects of hydrothermal temperature and Tween-80 on crystal phase and morphology of the obtained BiVO 4 were investigated. The crystal phase and morphology were characterized by X-ray diffraction, field emission scanning electron microscopy and UV–vis diffuse reflectance spectroscopy. The results indicated that the as-prepared decahedral BiVO 4 was monoclinic. The photocatalytic behavior for methylene blue (MB) degradation was enhanced with the assistance of an appropriate amount of hydrogen peroxide (H 2 O 2 ) under visible light irradiation. The photocatalytic tests indicated that the photocatalytic efficiency of decahedral BiVO 4 synthesized at 180 °C was 63.5%. However, BiVO 4 sample synthesized at 160 °C showed the highest photocatalytic degradation rate, up to 81.6%, due to its small size and crystal defects.
