Accelerated room-temperature crystallization of ultrahigh-surface-area porous anatase titania by storing photogenerated electrons†
Abstract
Room-temperature crystallization, a mild and energy-efficient process, shows important application potentials for developing functional materials. We significantly accelerated the crystallization of amorphous TiO2 at room temperature by storing photogenerated electrons and the resulting porous anatase titania exhibits ultrahigh surface areas up to 736 m2 g−1.
