Selective Preparation of Macroporous Monoliths of Conductive Titanium Oxides TinO2n–1 (n = 2, 3, 4, 6)

principal breakthrough in development of titania based solid electrolytes has been achieved via reduction of sol-gel derived macroporous monoliths with gaseous zirconium metal as Hiroshi Kageyama and colleagues reported in J. Amer. Chem. Soc. 2012.
