title: Prolonged Electron Lifetime in Ordered TiO2 Mesophyll Cell-Like Microspheres for Efficient Photocatalytic Water Reduction and Oxidation.
abstract: Mesoporous integrated TiO2 spheres composed of numerous orderly arranged nanocrystals with a reduced lattice-lattice interface connection, display an almost four times longer electron lifetime (350 ps) than the randomly aggregated nanoparticles (80 ps), and hence enhance the corresponding photocatalytic H2 and O2 generation.
