DEODORIZING PHOTOCATALYTICAL ACTIVATED CARBON AND PRODUCTION THEREOF

PURPOSE: To obtain deodorizing photocatalytical activated carbon having high gas adsorbing capacity and a wide adsorption spectrum, also equipped photocatalytical function and excellent in processability by uniformly mixing activated carbon precursor org. matter and a Ti-containing soln. and subsequently baking the resulting mixture to carbonize and activate the same to form titanium oxide supported activated carbon. CONSTITUTION: Deodorizing photocatalitical activated carbon based on titanium oxide supported activated carbon by uniformly mixing activated carbon precursor org. matter and a Ti-containing soln. and subsequently baking the resulting mixture to carbonize and activate the same. As the activated carbon precursor org. matter, any org. substance used as an activated carbon material can be adapted. As a Ti compd., thereis no special limit even if a material capable of being converted to TiO2 is used but titanium tetrachloride is industrially pref. Since supported titanium oxide is uniformly dispersed in activated carbon, this deodorizing photocatalyst has the original high specific surface area of activated carbon and, since this photocatalyst is strongly fixed to an adsorbent, it is excellent in processability even if a binder is not used.
