✦ Synopsis

Pyrene was adsorbed to a TiO 2 surface from water-alcohol mixture solutions at 25 °C and pyrene-TiO 2 particles were recovered by filtration. We found that the surface of TiO 2 thus recovered is relatively hydrophobic and pyrene is not decomposed but keep its fluorescence characteristics on the spectral measurement under ultraviolet excitation.
