Abstract

A new family of apatite materials Ca_10-xAg_x(PO₄)₆ (OH)_2-x□_x were synthesized, then studied using the decomposition reaction of isopropanol. The catalytic activity of the mixed apatites was observed to correspond mainly to dehydrogenation reaction features (the formation of acetone). This phenomenon has been tentatively related to the migration of Ag⁺ ions towards the surface and to their reduction to metallic silver under catalytic reaction conditions. The catalytic tests for the isopropanol decomposition reaction show that silver substituted hydroxyapatites were more actives than pure hydroxyapatite.
