PHOTOCATALYST WITH TITANIUM DIOXIDE USED AS SUBSTRATE AND ITS PRODUCTION |
| 摘要 |
PURPOSE: To produce a photocatalyst with titanium dioxide used as the SO3 contg. substrate. CONSTITUTION: Titanium dioxide contg. 0.2-20.0wt.% SO3 and having 50-300m<2> /g specific surface area and 80-250Åcrystalline diameter has superior photocatalytic activity. This photocatalyst is obtd. by adding sulfuric acid or ammonium sulfate to titanium dioxide or titanium hydroxide by 0.2-20.0wt.% (expressed in terms of SO3 ) and heating them at <=700 deg.C.
