Investigation on the photocatalytic degradation of pyrene on soil surfaces using nanometer anatase TiO2 under UV irradiation

Structural evolution and optical properties of C-coated TiO2 nanoparticles prepared by laser pyrolysis

“…However, one of the most important characteristic of TiO 2 anatase phase is the photocatalytic activity. It has been proven that persistent organic pollutant such as methyl orange [4], congo red [5] or detergents [6], decompose with high efficiencies when nanoparticles of TiO 2 anatase phase have been used [7,8]. Still, the use of TiO 2 in waste water treatments [9] or in hydrogen production by water molecular splitting [10] is reduced/restricted, mainly due to its wide band gap.…”

Photochemical Treatments of Textile Industries Wastewater

“…Photocatalysts dosage added to the reaction vessel is a major parameter affecting the photocatalytic degradation efficiency (Dong et al, 2010). Photocatalytic degradation efficiency increases with an increase in catalysts mass.…”

“…However, this is not general for all types of dyes (Hachem et al, 2001). Production of additional hydroxyl radicals occurs when hydrogen peroxide is added through the following mechanisms (Galvez, 2003& Dong et al, 2010 …”

Iron Oxide Mediated Degradation of Mutagen Pyrene and Determination of Degradation Products

“…Microbial [7]- [10] and photocatalytic [11]- [14] degradation of PAHs has been studied by various researchers. Limitation with microbial degradation is that the rate of degradation is slow for high molecular weight (more than three ring) PAHs [15].…”
