Abstract/OtherAbstract:
|
Photocatalytic activity of bismuth vanadate (BiVO(4)) for acetaldehyde decomposition under visible light irradiation was improved by inclusion of a nanocomposition of silica as an adsorbent material and loading of platinum (Pt) or trivalent iron ion (Fe(3+)) as reduction cocatalysts. Addition of silica enhanced photocatalytic activity due to improvement of adsorption ability, but total decomposition of acetaldehyde was not observed within 24h of visible light irradiation. For further improvement of photocatalytic activity, BiVO(4) with an optimized amount of silica composition were modified with Pt or Fe(3+). Photodeposition of Pt greatly increased photocatalytic activity, and acetaldehyde was totally decomposed within 24h of visible light irradiation. |
