In this study, BiVO4@Cu2O core-shell n-p heterojunctions based on BiVO4 nanospheres were synthesized via a template-free hydrothermal method. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS) analyses confirmed the core-shell structure of the as-obtained samples. A possible mechanism of Cu2O shell formation on the surface of BiVO4 nanosphere was proposed based on the characterization results, which involved a deposition-reduction-crystallizatio...
