Temporal analysis of products (TAP) study on oxygen storage properties over Pt−Rh/CeO2 catalyst

Temporal analysis of products (TAP) study on oxygen storage properties over Pt−Rh/CeO2 catalyst The oxygen storage capacity of CeO2, Ce0.9Pr0.1O2, Pt−Rh/CeO2 and Pt−Rh/Ce0.9Pr0.1O2 was investigated by conventional GC pulse method and transient pulse techniques. It is shown that incorporation of PrOy into CeO2 matrix strongly promotes oxygen storage capacity (OSC) measured using the transient pulse technique. The improvement of OSC at low temperature is observed in Pt−Rh loaded onto CeO2 and Ce−Pr catalysts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

The oxygen storage capacity of CeO2, Ce0.9Pr0.1O2, Pt−Rh/CeO2 and Pt−Rh/Ce0.9Pr0.1O2 was investigated by conventional GC pulse method and transient pulse techniques. It is shown that incorporation of PrOy into CeO2 matrix strongly promotes oxygen storage capacity (OSC) measured using the transient pulse technique. The improvement of OSC at low temperature is observed in Pt−Rh loaded onto CeO2 and Ce−Pr catalysts.
