制备了ＳＯ４２－／ＴｉＯ２（Ⅰ）、ＰＯ４３－／ＴｉＯ２（Ⅱ）、ＢＯ３３－／ＴｉＯ２（Ⅲ）系列固体酸。用ＩＲ、Ｒａｍａｎ光谱对该系列固体酸进行结构表征，结果表明ＳＯ４２－与ＴｉＯ２表面的结合为螯合式双配位结构和共价硫酸盐共存，ＰＯ４３－与ＴｉＯ２表面的结合为桥式三配位结构，ＢＯ３３－与ＴｉＯ２表面的结合为单齿单配位结构和螯桥混合式三配位结构共存。用由溶液中正丁胺的吸附等温线测定固体表面酸度的方法测定了样品的酸量，结果表明酸量大小为Ⅰ＞Ⅱ＞Ⅲ。用ＸＲＤ技术对该系列固体酸进行考察，衍射图分析提示该系列固体酸主要都为锐钛矿型晶型，但Ⅰ、Ⅱ、Ⅲ中又各自夹杂其它不同的晶型
SO42- / TiO2 (Ⅰ), PO43- / TiO2 (Ⅱ) and BO33- / TiO2 (Ⅲ) series of solid acids were prepared. The structure of the series of solid acids was characterized by IR and Raman spectroscopy. The results showed that the combination of SO42- and TiO2 surface was chelate bidentate and covalent sulfate, and the combination of PO43- and TiO2 was bridged tri-coordinate Structure, the combination of BO33- with TiO2 surface is monodentate single coordination structure and chelation bridge mixed three coordination structure coexist. The acidity of the sample was determined by measuring the acidity of the solid surface by the adsorption isotherm of n-butylamine in the solution. The results showed that the acidity was in the order of I> II> III. The series of solid acids were investigated by XRD, and the diffraction pattern analysis indicated that these series of solid acids were mainly anatase, but different types of crystals were mixed in each of Ⅰ, Ⅱ and Ⅲ
