A two-dimensional layered CeO2/Bi2O3 composite was synthesized by microwave solvothermal method. X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscope (FESEM), transmission (TEM), UV-Vis diffuse reflection spectroscopy (DRS), and photoelectron (XPS) were used to studied crystal structure, morphology, optical performance, elemental composition the surface elect...
