Hydroxyapatite Foam as a Catalyst for Formaldehyde Combustion at Room Temperature

Abstract

The excellent performance of hydroxyapatite, a novel non-precious metal catalyst, for formaldehyde (HCHO) combustion at room temperature is reported. Temperature-programmed surface reaction results indicated that hydroxyl groups bonded with the channel Ca(2+) may be responsible for adsorption/activation of HCHO.
