| Popis: | Three-dimensional (3D) CdMoO4 hierarchical structures constructed by single-crystalline nanoplates were prepared by a facile hydrothermal route. The obtained samples were systematically characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-Vis spectrophotometry. The morphology modulation of the as-prepared products could be easily tuned by changing the concentration of reactants, reaction temperature, molybdenum source, pH value and reaction time. The formation process of CdMoO4 hierarchical structures was related to the two-step growth, in which CdMoO4 main nanoplates were formed first in the synthesis, followed by self-construction of small nanoplates on both side of the main nanoplates in a regular fashion. The photocatalytic activities of CdMoO4 hierarchical structures and nanoplates for degradation of Rhodamine B (RhB) under ultraviolet (UV) light irradiation were also evaluated. CdMoO4 hierarchical structures constructed by nanoplates have a higher photocatalytic activity toward photo-degradation of RhB than that of CdMoO4 nanoplates, mainly due to their unique morphology and high crystallinity. |
