ESR STUDY OF ZrO₂ CATALYST

Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000

Received Date: 26 January 1995

The intensity of the signal(g=1.974) resulted from Zr³⁺ ion on the surface of ZrO₂ catalyst, increased with the calcination temperature and time, but that of the signal (g=2.003) resulted from F_s⁺ centers (surface oxygen ion vacancies with a single trapped electron) decreased and finally disappeared at 550℃.
