Non thermal preparation of photoactive titanium (IV) oxide thin layers

Notes on the photo-induced characteristics of transition metal-doped and undoped titanium dioxide thin films

“…The sol-gel method is one of the more successful techniques for preparing nanosized metallic oxides, often revealing enhanced photocatalytic activity [17,18]. The sol-gel-derived precipitates are amorphous in nature, requiring further heat treatment at high temperatures to induce the inevitable crystallization [19][20][21][22]. Photoactivity of crystal TiO 2 arises from the photo-generated electrons and holes.…”

Advancement of Sol-Gel–Prepared TiO2 Photocatalyst

“…Photocatalytic activity of TiO 2 is strongly influenced by the synthesis condition and methodology. Various methods have been applied for synthesis of TiO 2 photocatalyst: electrochemical [7,8], combining inverse micelle and plasma treatment [9], dip coating [10], two step wet Advancement of Sol-Gel-Prepared TiO 2 Photocatalyst http://dx.doi.org/10.5772/intechopen.68357 chemical [11], precipitation [12], thermal (hydrothermal and solvothermal) [13,14], chemical solvent and chemical vapor decomposition (CSD and CVD) [15,16], ultrasonic irradiation [17], two-route sol-gel [18], and sol-gel [19][20][21]. Sol-gel method is a technique to improve the physicochemical and electrochemical properties of TiO 2 nanocrystalline.…”

Microwaves in Photochemistry and Photocatalysis

“…1) From titanium(IV) isopropoxide, Ti(i-PrO) 4 [41]: The titania sol was prepared by hydrolysis of Ti(i-PrO) 4 according to the method described by Kluson et al [42]. The hydrolysis was carried out in the reverse micelles of Triton X-100 in cyclohexane.…”
