Abstract
Abstract In this paper, octahedral K 2 Ta 2 O 6 nanocrystals have been synthesized by a single-step hydrothermal method. Then the visible-light-driven plasmonic Ag–K 2 Ta 2 O 6 nanocomposite photocatalysts are prepared by a photochemical reduction process. The product was characterized using various techniques, such as X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), UV–visible diffuse-reflectance spectroscopy (DRS). The results show that the Ag nanoparticles are uniformly loaded on the surface of the K 2 Ta 2 O 6 . The prepared Ag–K 2 Ta 2 O 6 exhibits an efficient photocatalytic activity for degradation of tetracycline (TC) under visible-light irradiation and shows good repeatability and stability. In particular, the highest photocatalytic activity at the nominal atomic ratio of silver to tantalum as 3%, which is more than 3 times that of pure K 2 Ta 2 O 6 .
