Photodeposition of Hydroxyapatite into a Titanium Dioxide Nanotubular Layer Using Ca(EDTA) Complex Decomposition
A new photocatalytic hydroxyapatite (HA) synthesis method has been developed. This method is based on the unique ability of the TiO<sub>2</sub> photocatalyst to decompose the Ca(EDTA) complex under UV illumination. As a result, released Ca<sup>2+</sup> ions react with PO<s...

| description | A new photocatalytic hydroxyapatite (HA) synthesis method has been developed. This method is based on the unique ability of the TiO<sub>2</sub> photocatalyst to decompose the Ca(EDTA) complex under UV illumination. As a result, released Ca<sup>2+</sup> ions react with PO<sub>4</sub><sup>3−</sup> ions forming the HA particles. The photocatalytic formation of hydroxyapatite is found to have a fractional order, which may indicate the complex reaction mechanism and the presence of several limiting stages. The TNT-HA samples were studied by XRD, FTIR, SEM, GDOES, and biocompatibility study. High biocompatibility of the surfaces is proven by pre-osteoblast cell growth. |
