Abstract Photocatalytic activity and surface friction variation were evaluated on Ti-doped hydroxyapatite (Ti-HAp) and anatase-type TiO2 powders under UV illumination. Although the adsorption capability of Ti-HAp against gaseous 2-propanol (IPA) was greater than that of anatase, photocatalytic decomposition activity and water adsorption capability of Ti-HAp under UV illumination were inferior to those of anatase. Experiments using powder/epoxy composites revealed that Ti-HAp didn’t exhibit photo-induced hydrophilicity. The surface friction force variation of anatase under UV illumination was similar to previously reported trend for rutile ceramics. That of Ti-HAp exhibited a different trend, suggesting that its surface was originally more hydrophobic than anatase.
