Abstract

Ag-decorated TiO2 (Ag-TiO2) photocatalytic membranes have been fabricated by using Pluronic P-123 as a pore-forming and structure-directing agent. Six different hierarchical architectures were obtained by multilayer coating of different Ag-TiO2 sols. The porous structure of the resulting layers could be fine-tuned by altering the amounts of P-123 and AgNO3 added during the preparation of TiO2 sols. Physico-chemical and morphological properties of different Ag-TiO2 layers were thoroughly investigated. Ag nanoparticles were successfully incorporated into the TiO2 matrix. The Ag-TiO2 membranes possessed multi-functionality of membrane retention, Ag-enhanced TiO2 photocatalytic activity and anti-bacterial action. They were evaluated through experiments using a batch reactor and a photocatalytic membrane reactor (PMR). The best performing membrane was able to remove up to 1007 mg m(-2) h(-1) of Rhodamine B in the PMR. Two phenomena (photocatalytic degradation and adsorptive-membrane retention) that were responsible for the RhB removal were evaluated. In the batch reactor operated in dark, the membranes were able to remove greater than 5-logs of Escherichia coli. The membrane with the highest percentage of Ag incorporated was able to remove close to 7-logs of E. coli when operated in the PMR.

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.
