Paper Title:
Preparation of TiO2 Thin Films Using Inorganic Peroxo Titanic Complex and Autoclaved Sols as Precursors
  Abstract

A new sol-gel method was introduced to prepare titanium oxides (TiO2) photocatalytic thin flms using peroxide (H2O2) and titanyl sulfate (TiOSO4) as raw materials. The TiOSO4 solution was recipitated by adding ammonia solution, then peptized with 30% H2O2 solution to get a yellow, table, neutral, and transparent liquid (peroxo titanic complex sol). When the peroxo titanic complex sol was autoclaved above 80°C for 2h, it changed to a stable, semitransparent sol containing eedle-like, ultra-fine anatase crystals less than 20nm in diameter. Titanium oxide (anatase) films sed for photocatalysis can be prepared on substrates by a dip-coating technique using peroxo titanic omplex and autoclaved sols.
