Although it is generally accepted that the catalytic activities of hydroxyapatites for the oxidative dehydrogenation of propane decrease upon addition of CCl4 into the feedstream, greater and stable activities have been found with copper-strontium hydroxyapatites (Cu-SrHAp) in the presence of CCl4-X-ray diffraction and X-ray absorption fine structure analyses of the catalysts used for the oxidation in the presence and absence of CCl4 demonstrate that deep reduction of Cu2+ to Cu-0 of Cu-species in Cu-SrHAp during the oxidation is suppressed by the introduction of CCl4, resulting in an enhancement of the activities of the catalysts in the presence of CCl4.
