Sonochemical synthesis of PbMoO4 nanoparticles and evaluation of its photocatalytic activity. |
| 초록 |
PbMoO4 nanoparticles were successfully obtained in the presence of ethylene glycol (EG) with the assistance of a prolonged sonication process. The nanoparticles were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), diffuse reflectance spectroscopy (DRS) and adsorption-desorption N2 isotherms (BET). The catalyst prepared sonochemically showed higher photocatalytic activity than PbMoO4 prepared by solid-state reaction in the degradation reactions of rhodamine B (rhB), indigo carmine (IC), orange G (OG), and methyl orange (MO) under UV-Vis light radiation. In order to elucidate aspects of the degradation mechanism of the organic dyes, some experimental variables were modified such as pH, O2 level in solution, and radiation source. In general, the photocatalytic activity for the degradation of organic dyes followed the sequence IC ＞ OG ＞ rhB ＞ MO. |
