AB  - Herein, we explore the idea of self-assembly of nearly monodisperse nanoparticles 
      as uniform building blocks to design highly crystalline mesoporous TiO(2) 
      nanoparticles, through evaporation-induced self-assembly (EISA) and hydrothermal 
      methods by using non-ionic Pluronic F127 and anionic surfactant SDS, respectively 
      as structure directing agents. The small- and wide-angle powder X-ray diffraction 
      and transmission electron microscopy (TEM) are used to characterize the 
      mesophases. N(2) adsorption-desorption studies and high-resolution TEM results 
      further reveal that mesopores are formed by the arrangement of the nanoparticles 
      of size ca. 4.0-5.0 nm for SDS-templated and 8.0-9.0 nm for F127-templated TiO(2) 
      nanoparticles with broad interparticle pore size distribution. Optical properties 
      of these nanomaterials are studied by UV-visible diffuse-reflectance 
      spectroscopy, photoluminescence (PL) and time-resolved fluorescence (TCSPC). 
      These nanostructured titania exhibited excellent catalytic activity in the 
      photodegradation of ecologically abundant dyes Methylene blue and Rose Bengal 
      under UV-visible light irradiation.
