Photocatalytic degradation of phenolic compounds with new TiO2 catalysts

Comparative study of alcohols as sacrificial agents in H2 production by heterogeneous photocatalysis using Pt/TiO2 catalysts

“…Due to its simplicity, one of the most economic procedures for TiO 2 synthesis is the sol-gel method. Our research team has developed a photocatalyst which has been shown in the literature to give highly competitive results when compared with the commercial Aeroxide P25 TiO 2 photocatalyst in photocatalytic processes of aerated degradation [29] and hydrogen production [30]. In the field of hydrogen production, the simplest modification that is made to the TiO 2 and which results in an increase in hydrogen production of up to 3 orders of magnitude is the deposition of metals on its surface.…”

Effects of operating parameters and additives on degradation of phenol in water by the combination of H2O2and hydrodynamic cavitation

“…Among those studies, H 2 O 2 was often used for degradation/ oxidation reaction. It is known that H 2 O 2 in combination with other conventional methods such as ultrasound/Fe [1], microwave and UV [2], ozone [3], photocatalysis [4], electrocoagulation process [5], and UV/Fe 2+ [6] have obtained better results than conventional method alone. Moreover, phenol mineralization by combined hydrodynamic cavitation and heterogeneous advanced Fenton processing was also reported [7].…”

Nano photo scouring and nano photo bleaching of raw cellulosic fabric using nano TiO2

“…In recent years nano crystalline titanium dioxide has attracted much attention as photo catalysts in special applications [12] including white pigment [13], environmental purification [14], UV-protection [15], self cleaning coating [16][17][18], decolorization effluent [19,20], antibacterial agent [21,22], phenol degradation [23], flame retardant [24,25] and as a co-catalyst in order to cross-link cellulose with poly carboxylic acids [26,27]. The optical generated products can be also depolymerized pectin in cotton [28].…”
