    摘要: Silver chloride thin film (SCTF) with high specific surface area was synthesized through
    precipitation reaction by adding sodium chloride solution on top of frozen silver nitrate solution.
    Effects of precipitation time and silver nitrate concentration on the morphology of SCTFs were
    investigated. SEM images show that small crystal AgCl grains forming rod-like structure appeared on
    the bottom surface of the SCTF. After exposure of SCTFs to UV light, clusters of silver atoms were
    formed on the surface of SCTF as indicated by XRD analysis. Six SCTFs were attached to interior
    wall of the photo-reactor using double sided adhesive tape for investigation of photocatalytic
    property of the films. Almost completed decolorization of orange II dye by SCTF can be achieved under UV light illumination within two hours. SCTFs made under different initial silver nitrate
    solution concentrations of 8.4 M, 4.2 M and 3.6 M have little impact on dye decolorization efficiency.
    The photocatalytic degradation of orange II dye by SCTF under visible light illumination is less
    efficient than that under UV light. Around 31% of color can be removed after two hours.
