Enhancement effect of TiO2 dispersion over alumina on the photocatalytic removal of NOx admixtures from O2–N2 flow

Sustainable Carbon Dioxide Photoreduction by a Cooperative Effect of Reactor Design and Titania Metal Promotion

“…Moreover, an exothermic process without any weight loss is observed between 400 °C and 600 °C. In agreement with literature data [79], this process can be ascribed to the phase transition from amorphous to crystalline titania in the anatase phase. In addition to that, from TG/DTA analysis, no other process exists due to impurities degradation.…”

Full scale demonstration of air-purifying pavement

“…This process involves a solid semiconductor catalyst, most often anatase titanium dioxide (TiO 2 ), which is activated with ultraviolet light of the appropriate wavelength. To date, a number of researchers have investigated the dynamics of the photocatalysis of nitrogen oxides [2][3][4][5][6][7][8]. Photocatalytic oxidation of NO x offers the following distinctive advantages: (1) no extra reactants are required and (2) NO x is converted to nitrates, a significantly less harmful material.…”

SO uptake and release properties of TiO2/Al2O3 and BaO/TiO2/Al2O3 mixed oxide systems as NO storage materials

“…Along these lines, ␥-Al 2 O 3 [14,19,32,36,[38][39][40][41][42] and/or ZrO 2 [43][44][45] are promising choices for the secondary oxides that can be used in combination with TiO 2 . It was reported that if sulfur-poisoned Ba/Pt/Al 2 O 3 catalyst was blended with non sulfurpoisoned Pt/TiO 2 catalyst, sulfur desorption from the Ba/Pt/Al 2 O 3 catalyst under rich conditions is improved [14].…”
