STUDIES ON UPS AND XPS OF O2 AND H2O ABSORPTION ON SURFACES OF SrTiO3
SrTiO3表面O2,H2O吸附的UPS,XPS研究

The presence of surface state originated from Ti3+ ion on reductive SrTiO3 surface has been observed. The action of Ti3+ on photodecomposition of water and the action of light irradiation on regeneration of activity are analysed.
