The performance of amodel photocatalyst (Degussa P25), immobilized onto quartz sand using a dry/wet physical deposition method has been studied in a fluidized-bed reactor. A simple model substrate, dilute oxalic acid, was ...

Commercial applications of photocatalysis in slurry reactors employing titanium dioxide particles present the disadvantage of the additional cost associated with the downstream catalyst separation. In past years a significant ...

Contamination by dyes is one of the main problems related to water and environment pollution. In recent years, the search for new alternatives for the appropriate treatment of organic wastewater compounds has intensified. ...

Different visible light responses of commercial TiO2photocatalysts are assessed for theirapplication in air decontamination. To do that the modified TiO2catalysts were immobi-lized on borosilicate glass plates according ...

This study reports the critical importance of the particle state in TiO2 immobilized photocatalysis. To address this, TiO2 coatings are prepared using two methods: an Air Assisted Spray with an Automatized Spinning Coating ...

Photodegradation of dicamba, an ionizable herbicide, using TiO2 supported on HZSM-11 zeolite was investigated. Four photocatalysts with different weight percentages (wt%) of TiO2 were evaluated: 3%, 10%, 30% and 50%. The ...

AmorphousTiO2 films were deposited on glass microbeads using a specially designed circulating fluidized bed plasma-CVD reactor. The film thickness was varied between 7 and 120 nm. While only little carbon impurity was ...
