摘要
The intensity of the signal(g=1.974)resulted from Zr+ ion on the surface or ZrO2 catalyst, increased with the calcination temperature and time, but that or 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℃.
