Ambient Light Reduction Strategy to Synthesize Silver Nanoparticles and Silver-Coated TiO2 with Enhanced Photocatalytic and Bactericidal Activities
Abstract
Under ambient light illumination, silver nanoparticles can be synthesized by a triblock copolymer induced reduction of [Ag(NH 3 ) 2 ] + ions in ethanol. Conventional chemical reducing agents, thermal treatment, and radiation sources are no longer necessary in this novel approach. A possible mechanism was proposed to explain the formation and stabilization of silver nanoparticles based on UV−vis absorption spectra and transmission electron microscopy results. This novel ambient light route has been successfully applied to deposit silver nanoclusters on TiO 2 . Silver nanoclusters of about 2 nm in size were found to strongly anchor to the TiO 2 nanoparticles with high dispersion. The resulting silver-coated TiO 2 material with optimal silver loading showed enhanced photocatalytic and bactericidal activities compared to the uncoated TiO 2 . The reasons for the enhancements of the activities were discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
