title: Photocatalytic activity of NaNbO(3) thin films.
abstract: NaNbO(3) thin films prepared by the sol-gel method had homogeneous microstructure with an average grain size of 15-25 nm and exhibited photoinduced hydrophilic conversion under UV irradiation. However, the films had little photocatalytic oxidation activity under UV irradiation. This is the first observation that NaNbO(3) undergoes photoinduced hydrophilicity under UV irradiation.
