A novel approach to the hydrothermal synthesis of anatase titania nanoparticles and the photocatalytic degradation of rhodamine B. Turkish Journal of Chemistry, 30(3), 333 - 343.1300-05271303-6130https://hdl.handle.net/11616/18721https://search.trdizin.gov.tr/yayin/detay/57926Abstract: A novel approach was developed for the synthesis of high-dispersed anatase nano-TiO2 by a hydrothermal process without solvent at 200 °C in 1 h. It was characterized using XRD, TEM, BET and elemental analysis. Nanoparticle-TiO2 was used as a photocatalyst by considering complete degradation of Rhodamine B (RB) dye. The photocatalytic reaction parameters such as photocatalyst amount, irradiation time and dye concentration were optimized and it was found that 0.125 wt% catalyst in 30 mg/L of RB aqueous solution is adequate for full degradation of RB in 50 min with 770 W/m2 irradiation power. Photocatalytic activity of the nanoparticle- TiO2 was compared with Degussa P-25 at optimum catalysis conditions determined for the nanoparticle- TiO2. It was concluded that when compared to Degussa P-25, the nanoparticle- TiO2 can be repeatedly used with increasing photocatalytic activity. The results revealed that the photodegradation of RB proceeds by pseudo first-order reaction kinetics in which the rate constant of the degradation is 0.132 min?1.trinfo:eu-repo/semantics/openAccessArticle30333334357926WOS:000239913800008Q3
