“…3 (Curve 1-3). Curves 1 and 2 report three broad peaks and one intense peak at 38.01°, 47.5°, 54.20° and 25.1°, which are firmly indicative of TiO 2 of anatase phase [17]. Additionally curve (3) shows a few small peaks at 27.3°, 36.0° and 39.60°, and 41.2° which are closely related to rutile phase.…”

Photocatalytic Degradation of Different Dyes Using TiO2 with High Surface Area: A Kinetic Study

et al. 2013

Nanocrystalline TiO 2 was synthesized by using one step sol-gel method and characterized by SEM, XRD and EDS. UV-Vis spectroscopic technique has been used for studying the photocatalytic degradation kinetics of methylene blue (MB) and congo red (CR). A comparative study with commercial TiO 2 (P25) was also done to find out the effectiveness of this synthesized TiO 2 . The synthesized TiO 2 exhibited a high photocatalytic activity for the degradation of MB and CR but the commercial TiO 2 was more efficient.

Photocatalytic abatement of o-xylene using adsorption enhanced ZnO/GAC catalyst in a continuous flow reactor: Catalytic potential, Fate of o-xylene and its by-products

Photocatalytic abatement of o-xylene was investigated by immobilized ZnO on granular activated carbon (ZnO/GAC) under UV irradiation. Immobilization of ZnO increased the breakthrough time and removal capacity by 51 and 57%, respectively, in optimal conditions. The catalytic potential of the ZnO/GAC (86.5%) for o-xylene removal was far greater than simple GAC (13.5%), at the optimum condition. The maximum removal capacity with ZnO/GAC (3.12g o-xylene /gZnO/GAC) was observed at 100 °C, while the maximum removal capacity of simple GAC (1.37 g oxylene/g GAC) was observed a t 20 °C. The main intermediates of the o-xylene oxidation in photocatalytic process with GAC were methanoic acid, o-nitro-p-cresol, phenylmethanal, and methyl di-phenyl-methane. ZnO/GAC can highly catalyze the degradation of o-xylene in the presence of UV, with methanoic acid being the major intermediate desorbed from the bed. The results demonstrated that the ZnO/GAC is an efficient option for the removal of VOCs and biohazards emitted from industrial streams.

“…Therefore, development of titanium dioxide based photocatalysts anchored to supporting materials with large surface areas would be of great significance. It can not only avoid the disadvantages of filtration and suspension of fine photocatalyst particles, but also lead high photodecomposition efficiency [8]. More recently, titanium dioxide has been extensively explored as a coating material for textiles to provide functions such as antibacterial activity, UV protection, and self-cleaning.…”
