Solvent Synthesis,Growth Mechanism and Photocatalytic Properties of AgInS_2 Nanoplate and Nanoparticle

Orthorhombic AgInS_2 nanoplate and nanoparticle were synthesized using pyridine and 1-dodecanethiol as the solvent.The obtained products were characterized by X-ray diffraction(XRD),field-emission scanning electron microscope(FESEM),field-emission transmission electron microscope(FETEM),and the possible growth mechanism of AgInS_2 was also proposed by the exploration of reaction temperature and time.Meanwhile,the bandgap of AgInS_2 was calculated by the UV-Vis diffuse reflectance spectrum,and the photocatalytic activity was also investigated.Those experimental results indicate that the reaction temperature,reaction time and solvent have an influence on phase and morphology of AgInS_2,and both AgInS_2 nanoplate and nanoparticle have some ability on photocatalytic degradation of organic dyes under UV-Vis light irradiation.
