To overcome rapid electron-hole recombination and low adsorption capacity of single g-C3N4 photocatalyst, the present work reports on the fabrication of two kinds of visible-light-driven composite photocatalysts (g-C3N4/kaolinite and g-C3N4/illite composites). 2D/2D assembly was successfully achieved in this work. Furthermore, the as-synthesized composites exhibited significantly enhanced photocatalytic...
Graphitic carbon nitride (g-C3N4) has attracted enormous research attention as a promising low cost, visible-light driven semiconductor photocatalyst. However, low photoabsorption efficiencies and unsatisfactory charge separation limit the potential of g-C3N4 in many applications, motivating attempts to manipulate the structure and electronic properties of g-C3N4 to achieve improved performance. Here...
The (CO3)2− self-doped Bi2O2CO3/g-C3N4 (C-BOC/g-C3N4) unique 2D-2D heterostructure has been developed via a mixed-calcination method. This heterostructure is confirmed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), SEM-mapping, and diffuse reflection spectroscopy (DRS). Due to the charge interaction,...
