摘要: Abstract Ball-in-ball CuSCN hollow architecture is successfully synthesized by a facile one-pot aqueous solution method in the presence of poly(vinylpyrrolidone) at room temperature. The as-synthesized products are characterized X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission (HRTEM), photoelectron spectroscopy (XPS), UV–vis diffuse reflectance absorption spectra (DRS) and nitrogen adsorption–desorption measurement. A possible formation mechanism for spheres difference solubility (Ksp) CuBr or chemical self-transformation proposed based on experimental observations. band gap energy sphere estimated to be 3.77 eV results optical BET specific surface area ball-in-ball calculated 30.5 m2/g it has bimodal mesoporous structure from investigation.
