Even with rigorous environmental regulations, phenol still is a major contaminant. One possible solution is the use of heterogeneous photocatalysis due to low chemical addition, feasibility and reliability to be implanted on cost-effective industrial process. TiO2 is the most employed photocatalyst because of its favorable (photo) chemical properties and ZnO is considered one of the best altern...

Trials on ciprofloxacin removal from real aqueous systems were performed using a photocatalytic membrane reactor with catalyst in suspension. Four sets of four treatment cycles carried out and experimental results processed the statistical point view order to assess reproducibility. Global efficiencies more than 99.85% obtained for all cycles. Coupling degradation process allowed separation reu...

In Korea, the issue of particulate matter pollution is growing, and many solutions are being developed to deal with it. Photocatalytic technology has been found be helpful in removing precursors such as nitrogen oxides that cause matter. a microcosm setup, ISO 22197-1 successfully used quantify removal from specimen which photocatalyst applied. However, owing lack suitable tools, on-site measur...

3D-printed polyamide structures coated with TiO2 nanoparticles were obtained by a simple impregnation method. This novel type of 3D reactor was evaluated for its photocatalytic activity towards the degradation methylene blue under UV light using 360-degree rotating stage. Rotation improved all structures. The best structure showed 94.1 % degradation, after 180 min irradiation rotation.

This paper presents a study on the preparation method for Ag-TiO2 nano particles. Photodeposition of silver on TiO2 nanoparticles was carried out by adding a desired volume of aqueous AgNO3. Ag-deposited TiO2 catalyst was characterised by XRD, TEM, SEM. The Ag-TiO2 catalyst was evaluated for their photocatalytic activity towards the degradation of Malachite green (MG) under UV irradiation. An a...
