Fabrication of Rutile TiO2 Foils with High Specific Surface Area via Heterogeneous Nucleation in Aqueous Solutions

Abstract

Abstract Rutile TiO2 foils with high specific surface area were fabricated through heterogeneous nucleation on substrates in acidic aqueous solutions of titanyl sulfate. Rutile crystals were directly deposited even at a near room temperature in the solutions at the conditions around the boundary between the Ti(IV) soluble species and the TiO2 crystal in the phase stability diagram of the Ti(IV)-H2O system.
