Abstract

Herein, a visible-light-active BiOCl/Ag6Si2O7 nanocomposite with a strong interfacial interaction p–n heterojunction structure was fabricated via a simple deposition–precipitation method and subsequently investigated as a novel photocatalyst for the first time. The structure, morphology, and optical properties of the prepared samples were thoroughly characterized by field-emission scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM, X-ray diffraction, diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The photocatalytic performance was evaluated by monitoring the degradation of methyl orange (MO) and phenol and the photocurrent generated under visible-light irradiation. The BiOCl/Ag6Si2O7 photocatalyst increased significantly its photocatalytic performance compared to the pristine BiOCl and Ag6Si2O7 materials. This enhancement could be ascribed to the strong visible light absorption and the effective separation of the photogenerated electrons (e) and holes (h+) by the internal electrostatic field generated at the junction region. In addition, BiOCl/Ag6Si2O7 showed stable photocurrent over long times and cyclic degradation of MO, thereby demonstrating potential applications in the field of environmental remediation.
