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 Fs+ centers (surface oxygen ion vacancies with a single trapped electron) decreased and finally disappeared at 550℃.
