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.
