AB  - We have developed a new facile procedure for manufacturing crystalline thin films 
      of SnO2 with a uniform mesoporous architecture and full crystallinity of the 
      walls. The procedure is based on the evaporation-induced self-assembly (EISA) of 
      prehydrolyzed tin oxide precursor directed by a commercially available Pluronic 
      polymer. The formation of the tin oxide precursor, which can be self-assembled 
      into a mesoporous structure, is achieved by an addition of ammonium hydroxide to 
      a tin tetrachloride solution. The relative concentration of ammonium hydroxide as 
      well as the duration and temperature of the hydrolysis reaction influence 
      significantly the properties of hydrolyzed tin oxide species and the 
      mesostructure assembled from them. The films coated from these precursor 
      solutions and calcined at 300  degrees C to 400  degrees C exhibit a well-developed worm-like 
      porosity with a wall to wall distance of ca. 18 nm, a surface area of up to 50 
      cm2 cm(-2) (corresponding to 55+/-5 m2 g(-1)), and high crystallinity.
