Synthesis of Nanostructured Silver/Silver Halides on Titanate Surfaces and Their Visible-Light Photocatalytic Performance
Dense and uniform silver halides AgX (X = Cl, Br, I)
nanoparticles
were successfully fabricated on layered titanate nanowired honeycomb
(TNHC) thin films. The growth of AgX nanocrystals was carried out
through two steps. Firstly, ion-exchange was employed to incorporate
Ag<sup>+</sup> ions into the interlayer of the titanate nanowires.
Secondly, hydrogen halide (HX) solution was rapidly injected onto
the ion-exchanged silver TNHC surface to generate nanosized AgX particles
on TNHC films. The effect of the reaction time, solution pH, and concentration
of halide anions on the morphology of the AgX photocatalysts has been
studied. Followed by light-irradiation, the optimized Ag/AgX thin
films exhibited excellent degradation performance under visible light
because of localized surface plasmon resonance effect
