Abstract
Reversible formation of F+-centers was observed over platinum promoted sulf ated zirconia in the presence and absence of hydrogen. The intensity of ESR signal of F+-centers was increased by treatment in He stream and it was de creased rapidly by supply of hydrogen in gas phase. This behavior seems to be related to proton spillover.
