摘要: 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 recipitated by adding ammonia solution, then peptized with 30% H2O2 get a yellow, table, neutral, transparent liquid (peroxo titanic complex sol). When the peroxo sol autoclaved above 80°C for 2h, it changed stable, semitransparent containing eedle-like, ultra-fine anatase crystals less than 20nm in diameter. Titanium oxide (anatase) films sed photocatalysis can be prepared on substrates dip-coating technique omplex sols.
