Precipitated nanosized titanium dioxide for electrochemical applications

Synthesis, morphology and electrochemical properties of TiO2 microspheres

“…7 with the results of our previous studies [14] of nanosized (15-20 nm) non-aggregated TiO 2 . Examining these data one can conclude that the non-aggregated samples have much better electrochemical properties than the microspheres.…”

“…As in Ref. [14], except the main cathode and anode processes occurring at 1.7 and 2.0 V, respectively, washed-up peaks of insertion and deinsertion of lithium to and from amorphous TiO 2 are visible as noticed in Fig. 5 by arrows.…”

“…In this paper, a novel method for the synthesis of TiO 2 microspheres in «mild» conditions, viz., in solutions of moderate concentration, at medium temperature and ambient pressure is presented, and morphology and electrochemical properties of the material obtained are described. Following our previous work [14] and unlike other approaches [1][2][3][4][5][6][7][8][9][10][11][12][13], we use TiCl 4 instead of organic derivatives of titanium as a raw material.…”

Hydrothermal synthesis of anatase nanoleaves and size dependence of anatase–rutile transformation upon heating

“…In our previous work [14], we have found that hydrolytic precipitation of TiO 2 from titanium chloride can serve as a convenient alternative to the method of hydrolysis of organic derivatives of titanium. In particular, it has been noticed that depending on the conditions of the synthesis, titania samples having strictly different properties can be obtained.…”

“…Continuing our efforts directed towards obtaining nanosized TiO 2 -based electrode materials by means of hydrolysis of titanium chloride [14,15] we have subjected this hydrolytic titania to the hydrothermal treatment in concentrated solutions of LiOH instead of NaOH. In this paper, we describe the products obtained from the aged precipitate synthesized by adding TiCl 4 to LiOH and present the data regarding their transformations upon heating.…”
