Temperature-programmed Desorption of Oxygen from La–Sr–Co–Fe Perovskite in Atmospheres with Varying Oxygen Partial Pressure

Temperature-programmed Desorption of Oxygen from La–Sr–Co–Fe Perovskite in Atmospheres with Varying Oxygen Partial Pressure

A temperature-programmed desorption technique under atmospheres with variable partial pressure of oxygen has been developed using a homemade fixed-bed flow reactor equipped with a yttria-stabilized zirconia (YSZ) oxygen sensor as a detector of oxygen desorbed from a sample. Its significance has been...

Zusammenfassung:A temperature-programmed desorption technique under atmospheres with variable partial pressure of oxygen has been developed using a homemade fixed-bed flow reactor equipped with a yttria-stabilized zirconia (YSZ) oxygen sensor as a detector of oxygen desorbed from a sample. Its significance has been verified for the particular catalytic material of La–Sr–Co–Fe–O perovskite-type oxide.
