摘要：

通过在水溶液中将由磷酸氢氨和硝酸钙制得的“盐溶液”与由钛酸正丁酯和冰醋酸制得的“酯溶液”反应,并将产物在800 ℃下活化4 h,获得二氧化钛与羟基磷灰石的纳米复合物.用X射线衍射、红外光谱和透射电镜(TEM)对纳米复合物的组成和结构进行了研究.红外光谱显示了TiO2和PO4-3的两个特征峰,证实了纳米复合物由二氧化钛和羟基磷灰石组成.透射电镜表明,羟基磷灰石包覆在二氧化钛微晶颗粒的表面,形成颗粒尺寸约为100 nm的二氧化钛/羟基磷灰石复合物.X射线衍射图谱显示所得的二氧化钛与羟基磷灰石纳米复合物在2θ = 30°～35 °处出现3个新的衍射峰,说明纳米复合物的二氧化钛与羟基磷灰石界面上可能生成了分子复合物.
Abstract:

The nano-composite of TiO2 anatase and hydroxyapatite was prepared via the aqueous reaction of “salt solution” made from (NH4)2HPO4 and Ca(NO3)2 and “ester solution” made from acetic acid and tetrabutyl titanate followed by heating the solid product at 800 ℃ for 4 hours. The obtained white powder sample was characterized by X-ray diffraction, infrared spectrum and transmission electro-microscope (TEM). The infrared spectrum showed two character peaks, which were assigned to TiO2 and PO4-3 group and indicated the composite being formed by TiO2 anatase and hydroxyapatite. The size of the nano-composite is ca. 100 nm in the TEM image. Three additional diffraction peaks appeared between 2θ = 30° and 35° for the composite sample, which may suggest the molecular complex in the interface of TiO2 anatase and hydroxyapatite in the nano-composite．
