【 摘 要 】

Tetragonal YVO 4 nanoparticles of different sizes were successfully prepared through an ethylenediaminetetraacetate -mediated hydrothermal method. The crystalline structure and optical property were characterised by transmission electron microscopy (TEM), high resolution TEM, X-ray diffraction, photoluminescence spectra, and ultraviolet–visible diffuse reflection spectra, respectively. The as-prepared YVO 4 displayed excellent photocatalytic performance. Among them, sample S2 has the highest photocatalytic activity with a photodegradation efficiency of 85% within 180 min illumination, which is due to its smaller size and larger specific surface area. The investigation on the photocatalytic mechanism reveals that hydroxyl radical (•OH) is the main active species in the photocatalytic oxidation process.
