摘要：
The high quality ordered macroporous titania has been successfully synthesized with the hydrolysis of titanium tetrachloride (TiCl4) by heating the hydrochloric acid solution of TiCl4 which filled in polystyrene templates. In this method, there is no need of filling the interspaces of polystyrene template repeatedly and no introduction of organic impurities either. The best conditions of synthesizing ordered macroporous titania are found that the pH value is 2.0 similar to 2.5, the filling time is 3h and the calcination temperature for the filled templates is 500 degrees C. The macroporous titania synthesized show highly ordered structure and obvious photonic bandgap.
