Abstract

Abstract: Uniform mesoporous anatase hollow spheres with high crystallinity have been fabricated by an efficient method, in which biocompatible ethanedioic acid acts as the chelating agent during the Ostwald ripening process. The combination of high crystallinity, large surface area, and mesoporosity leads to an excellent photocatalytic activity. In solar water splitting, the hollow spheres exhibit remarkably enhanced photocatalytic performance that is 1.4 times of P25. Abstract : Enhance your chemistry ! Uniform mesoporous anatase hollow spheres with high crystallinity have been fabricated by an efficient method, in which the biocompatible ethanedioic acid acts as the chelating agent during the Ostwald ripening process. In solar water splitting, the hollow spheres exhibit remarkably enhanced photocatalytic performance that is 1.4 times that of P25.
