通过水热处理，制备了热稳定的纳米晶金红石型TiO 2颗粒与少量的P改性的混合物含有含钛的前体，这是通过在低温下老化的非晶TiO 2的稀HCl溶液，和少量的磷酸。产物的XRD分析和高温氮化样品的紫外-可见光谱表明，P原子在TiO 2结构中的引入有助于提高P改性TiO 2样品的热稳定性。
Thermally stable nanocrystalline rutile TiO2 particles modified with small amounts of P were prepared via hydrothermal treatment from mixtures containing Ti-containing precursors, which were obtained by aging diluted HCl solutions of amorphous TiO2 at a low temperature, and small amounts of phosphoric acid. XRD results of the products and UV–vis spectra of the samples nitrified at a high temperature suggest the incorporation of P atoms in the TiO2 structure, which contributes to the enhanced thermal stability of the P-modified TiO2 samples.
