Graphene-analogue boron nitride(BN) covered with AgI nanocomposites were successfully synthesized by a template-free in situ ultrasound-assisted method at room temperature. A set of characterizations technics like X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FE-SEM), transmission electron microscopy (TEM), UV-VIS Spectrophotometer, Fourier transformed infrared spectroscopy (FT-IR), and photoluminescence spectroscopy (PL) have been employed to know the structural and morphological nature. The results showed that the AgI nanostructures were grown on graphene analogue boron nitride sheets. The photocatalyst studies show that BN-AgI nanocomposites exhibit much higher photocatalytic activity and anti-photocorrosion than the pure AgI under visible-light irradiation. Among the BN/AgI nanocomposites (wt% of BN = 0.1, 0.2, 0.3, 0.4), BN/AgI (0.2wt%) has the highest photocatalytic activity by the degradation of Rhodamine B (RhB). And its catalytic efficiency goes up to 100% within 70 min. According these results, we are able to know how good the BN/AgI nanocomposites have photocatalytic efficiency under visible-light.
