Dehydration of Alginic Acid Cryogel by TiCl4 vapor: Direct Access to Mesoporous TiO2 @C Nanocomposites and Their Performance in Lithium-Ion Batteries.

摘要: A new strategy for the synthesis of mesoporous TiO2 @C nanocomposites through direct mineralization seaweed-derived alginic acid cryogel by TiCl4 a solid/vapor reaction pathway is presented. In this synthesis, can have multiple roles; i) template, ii) carbon source, and iii) oxygen source precursor, . The resulting @alginic composite was transformed either into pure calcination or pyrolysis. By comparing with nonporous composite, importance mesopores on performance electrodes lithium-ion batteries based clearly evidenced. addition, matrix in nanocomposite also showed electrochemical activity versus lithium ions, providing twice capacity acid-derived (A600). Given simplicity environmental friendliness process, could satisfy main prerequisites green sustainable chemistry while showing improved as negative electrode batteries.
