In situ facile fabrication of Z-scheme leaf-like β-Bi2O3/g-C3N4 nanosheets composites with enhanced visible light photoactivity

In this work, leaf-like β-Bi2O3/g-C3N4 nanosheets composites were synthesized via a simple in situ method. β-Bi2O3/g-C3N4 nanocomposites were obtained via calcining the mixtures of g-C3N4 and metallic Bi, while, at the same temperature, in the absence of g-C3N4, metallic Bi formed α-Bi2O3. The presence of β-Bi2O3 in the composite was demonstrated by X-ray diffraction, high-resolution transmission electron microscopy (HRTEM) and X-ray...
