C–N–S tridoped TiO2 for photocatalytic degradation of tetracycline under visible-light irradiation

PtOx-SnOx-TiO2 catalyst system for methanol photocatalytic reforming: Influence of cocatalysts on the hydrogen production

“…Pt was introduced by impregnation followed by either reduction in H 2 at 400 o C or calcination at 300 o C. TEM, XRD and Raman spectroscopic measurements proved that TiO 2 existed in the form of aggregates of polycrystalline anatase with primary particle size of [15][16][17][18][19][20] nm in each of the samples. Photocatalytic hydrogen production was influenced by the combined effect of many parameters.…”

“…Benefits derived from preparing TiO 2 by sol-gel method include the synthesis of nanosized crystallized powder of high purity at relatively low temperature, resulting in homogeneity of the prepared materials. Sol-gel methods gives possibility to introduce doping elements [11][12][13][14] or their combination simultaneously [15], to prepare composite type TiO 2 -based materials [16,17]. Sol-gel method is a possible way to obtain coatings or nanocoatings [18], porous films [19] or ordered mesoporous structures [20,21].…”

Advanced Oxidation Processes in Food Industry Wastewater Treatment – A Review

“…Degussa P-25 TiO 2 catalyst is probably the most active catalyst in photocatalytic reactions however its optimum effective will always be strongly dependent on the type and concentration of the treated pollutant (Gogate & Pandit, 2004a). In several studies, the doping of TiO 2 with metals, such as, platinum (Hufschmidt et al, 2002), silver, zirconium and iron (Kment et al, 2010) as well as, sulphur, carbon and nitrogen (Menendez-Flores et al, 2011;Wang et al, 2011) has been proven to enhance the activity of the catalyst. …”

Visible Light Photocatalytic Degradation of Azo Dye and a Real Textile Wastewater Using Mn, Mo, La/TiO2 /AC Nanocomposite

“…Among these semiconductors, nano-sized TiO 2 has received much attention, because of its wide applications in semiconductors, sensors, antibacterial and hygienic materials, photocatalysts, and solar cells 9 . TiO 2 exhibits high photocatalytic activities, high turnover, long-term photostability, cost-effectiveness, and non-toxic nature [10][11][12][13] . Therefore, it has been extensively used in various photocatalytic fields, such as water and gas streams purification and degradation of organic pollutants.…”
