Abstract

Monolithic conductive titanium oxides Ti nO 2n-1 (n = 2, 3, 4, 6) with well-defined macropores have been successfully prepared as a single phase, via reduction of a macroporous TiO 2 precursor monolith using zirconium getter. Despite substantial removal of oxide ions, all the reduced monoliths retain the macropore properties of the precursor, i.e., uniform pore size distribution and pore volume. Furthermore, compared to commercial porous Ebonex (shaped conductive Ti nO 2n-1), the bulk densities (1.8 g cm -3) are half, and the porosities (60%) are about 3 times higher. The obtained Ti nO 2n-1 (n = 2, 3, 4, 6) macroporous monoliths could find applications as electrodes for many electrochemical reactions. © 2012 American Chemical Society.
