Effects of Particle Size of TiO2 on Photocatalytic Degradation of Methylene Blue in Aqueous Suspensions
Abstract
The influence of particle size of TiO 2 on the photocatalytic degradation of methylene blue (MB) in a suspended aqueous solution has been studied. The results suggested that the adsorption rate and adsorbability of MB on suspended TiO 2 particles increased as the particle sizes of TiO 2 decreased. Photocatalytic activity of TiO 2 also increased as the particle size of TiO 2 became smaller, especially when the particle size is less than 30 nm. The half-life ( t 0.5 ) of the photocatalytic degradation of MB also decreased as the particle sizes of TiO 2 decreased. The first-order reaction rate constant for photodegradation of MB increased as the particle size of TiO 2 decreased. The initial degradation rate of MB in a suspended model was higher than that of a fixed-bed model. This will overcome the difficulty of preparation of ultrafine TiO 2 catalyst particles. Once the problem of separation of fine TiO 2 particles is solved, a TiO 2 suspended photoreactor could be provided on an industrial basis.

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.
