Abstract

Several samples of exchanged cobalt/calcium (Co²⁺/Ca²⁺) hydroxyapatite were synthesized and characterised by XRD, IR and UV-visible spectroscopy. The level of Co²⁺/Ca²⁺ exchanged was limited to 1.35 wt% of Co and the Co²⁺ ions incorporated in the phosphate matrix were mainly hosted by octahedral sites. The catalytic activity of these materials was measured in the oxidative dehydrogenation of ethane into ethylene in the 450-550°C range. The global conversion and the ethylene yield increase with temperature and depend upon the cobalt content. They reached 35% and 22% at 550°C respectively for a Co wt% of about 1%.
