Facile synthesis of visible-light-active BiOI modified Bi2MoO6 photocatalysts with highly enhanced photocatalytic activity
Source abstract
Abstract
Abstract Highly efficient BiOI/Bi 2 MoO 6 photocatalysts were successfully synthesized by a facile and economical deposition-precipitation method at lower temperature, and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), energy dispersive X-ray (EDX) and UV–vis diffuse reflectance spectroscopy (DRS). The photocatalytic performance of BiOI/Bi 2 MoO 6 was examined and evaluated by the decomposition of methyl orange (MO) and phenol under visible-light irradiation. The as-prepared BiOI/Bi 2 MoO 6 composites exhibited much superior photocatalytic activities than pure BiOI and Bi 2 MoO 6 in the photodegradation of the target organic pollutants. The synergistic effects were found to lead to an improved photo-generated carrier separation. Additionally, on the basis of trapping experimental results and band structure analysis, a possible photodegradation mechanism was proposed to elucidate the photocatalytic process and the reuse experiments were employed to confirm the durability and stability of the catalysts.
