Abstract

Calcium phosphates with metal ions are expected to show interesting characteristics, such as catalytic activity, as well as high ability to adsorb organic substances. We assumed that the organic substances adsorbed on calcium phosphates could be decomposed by treatment with hydrogen peroxide (H 2O2) if the catalytic activity for the decomposition of H2O2 can be introduced to calcium phosphates. We synthesized hydroxyapatite (HAp) containing Ni or Co ions, and octacalcium phosphate (OCP) containing Ni, Co or Mn ions. The HAp containing Co ions and the OCP containing Co or Mn ions showed catalytic activity for the decomposition of H2O2.
