Abstract: 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+ 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.
