Abstract

The present study demonstrates that H₂SO₄ treatment of TiO₂ surface provides higher photocatalytic decomposition efficiency on gaseous toluene under a proper condition. Deactivation was less remarkable for H₂SO₄-treated TiO₂ than for pure TiO₂ with repeated toluene injections. This result is attributable to the assist of the decomposition of intermediates by surface strong acid itself or resultant high quantum yield by decreasing recombination possibility between electrons and holes on the powder surface.
