Preparations and characterization of novel photocatalysts with mesoporous titanium dioxide (TiO2) via a sol–gel method

Parameters affecting the photocatalytic degradation of dyes using TiO2-based photocatalysts: A review

“…The advantage of these methods (wet chemical methods, which include sol-gel) is that they facilitate the synthesis of nanometer sized crystallized TiO 2 powder of high purity at relatively low temperature [115]. Other Researchers used modified sol-gel method [121,122], ultrasonic assisted sol-gel method [72], aerogel method [123], method similar to sol-gel [38], sol-gel and photo-reductive decomposition [39], precipitation [43,124], two-step wet chemical method [91], and extremely low temperature precipitation [125].…”

Tm-doped TiO2 and Tm2Ti2O7 pyrochlore nanoparticles: enhancing the photocatalytic activity of rutile with a pyrochlore phase

“…This is due to its high chemical and biological stability, low cost, excellent electronic and optical properties, and the strong oxidation capacity of its photogenerated holes [1–2]. Photocatalytic activity depends on several catalytic properties, such as band gap energy, specific surface area, the extent of crystallinity, the structure of the material, etc.…”

Novel titanium dioxide structure templated from filter paper scales

“…5a, the obvious weight loss in Fig. 5b in the temperature range 260-650 • C is attributed to the overlap of three processes, such as condensation of the hydroxyl groups linked to titanium [28], crystallization from the amorphous phase to the octahedrite crystal [29], and decomposition of the filter paper template. It can be deduced that this overlap could have an effect on the crystallization.…”
