Co/Sr-hydroxyapatite catalyst (Co/Sr₁₀(PO₄)₆(OH)₂: Co/ Sr-P) shows high activity and low carbon formation on ethanol steam reforming. H₂-TPR measurements revealed that the Co species supported on Co/Sr-P was reduced only slightly more than that on typical Co/α-Al₂O₃. XAFS measurements revealed that Co²⁺ species was observed mainly on the Co/Sr-P catalyst after H₂-reduction at reaction temperature of 823 K. Co²⁺, i.e. CoO particle, on Co/Sr-P catalyst plays an important role as an active site for ethanol steam reforming with high coke resistance.
