چکیده

Samarium-doped ZnO hierarchical micro/nanospheres (Sm/ZnO) were synthesized via a facile and surfactant-free chemical solution route. The obtained products were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), UV–visible diffuse reflectance spectroscopy (UV-vis DRS) and photoluminescence spectroscopy (PL). Photocatalytic test showed that the Sm/ZnO exhibited higher activity for phenol degradation compared to pure ZnO. The photocatalytic enhancement of Sm/ZnO was attributed to factors such as improved optical absorption property and improved lifetime of the

Visible Light-Driven Photocatalytic Performance of N-Doped ZnO/g-C3N4 Nanocomposites

N-doped ZnO/g-C3N4 composites have been successfully prepared via a facile and cost-effective sol-gel method. The nanocomposites were systematically characterized by XRD, FE-SEM, HRTEM, FT-IR, XPS, and UV-vis DRS. The results indicated that compared with the pure N-doped ZnO, the absorption edge of binary N-doped ZnO/g-C3N4 shifted to a lower energy with increasing the visible-light absorption ...
