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 verified for the particular catalytic material of La-Sr-CoFe-O perovskite-type oxide.
