Abstract
Hydroxyapatite (HAp) is attracting interest as a heterogeneous catalyst due to its “zeolitic” properties that allow tailoring of chemically active surface sites for specific applications. Here, the crystallographic modification of HAp through incorporation of zinc (Zn2+) was studied using diffraction and spectroscopic techniques. The preferential displacement of tunnel calcium (Ca2+) by covalently bonded Zn2+ inhibits crystal growth and promotes the retention of an amorphous (10-20 wt%) component. In combination, these factors create chemically active surfaces that allow Zn-HAp materials to effectively absorb carbon monoxide (*characteristic vibration at ~1711 cm-1) and catalyze the decomposition of 2-propanol. © 2012, Wiley-VCH Verlag GmbH & Co.
