- 論文の詳細を見る
TiO<SUB>2</SUB> microcrystallites of different sizes were prepared in Nafion and the energy diagrams of these were determined from the onset potential of photocurrents due to oxidation of tartrate ions and the bandgap energy which was estimated from absorption spectra. The smallest particle prepared in the present study had the diameter less than 2 nm and the bandgap energy of 3.95 eV. Photocatalytic activities of the TiO<SUB>2</SUB> microcrystallites prepared in Nafion for photodecomposition of acetic acid were very low compared to those of TiO<SUB>2</SUB> microcrystallites prepared in clay interlayers and were comparable to those of the latter photocatalysts obtained in the presence of SO<SUB>4</SUB><SUP>2−</SUP>, suggesting that sulfonate groups of Nafion made the photocatalytic activity of TiO<SUB>2</SUB> microcrystallites decrease.
