摘要：

X-ray photoelectron spectroscopy, X-ray diffraction, and temperature-programmed reduction were used to characterize Pt on both sulfated and nonsulfated zirconia. Upon air calcination of the sulfated sample at 600°C, Pt was reduced to the metallic state. In the case of nonsulfated samples, Pt remained in an oxidized form. It is proposed that SO2 produced by the decomposition of sulfate ions reduces Pt. © 1994 Academic Press, Inc.
