| Abstract: | The Ag-K2Nb2O6 nanocomposites are synthesized by a two-step method where the octahedral K2Nb2O6 is initially prepared by solvothermal reaction and then the Ag particles are anchored onto the surface of K2Nb2O6 through the photoreduction of AgNO3. The XRD, SEM, TEM, XPS, DRS are applied to characterize the structure, morphology and optical properties, which confirm that the Ag particles are successfully deposited on the surface of K2Nb2O6. Compared with the pure K2Nb2O6, the Ag modified K2Nb2O6 catalysts show an obvious enhancement catalysis under UV–Vis light, because that could efficiently promote the light absorption and the separation of photoelectrons and holes. |
