Titanium ethoxide [Ti(OEt)4] used in the preparation of organic-inorganic hybrid materials.

Aminobenzoic acid (AB) or aminosalicylic acid (AS) was used to modify Titanium ethoxide [Ti(OEt)4] to manage hydrolysis and condensation rates and to prepare the organic-inorganic hybrid materials. To test the structure and morphology of the hybrid material and the effects of the organic functional groups in sol-gel-processed hybrid TiO2 materials, several techniques were used, which included Fourier transform infrared spectroscopy, NMR, SEM, thermogravimetric analysis, and X-ray diffraction.

本研究以氨基苯甲酸（Aminobenzoic acid, AB）或氨基水杨酸（aminosalicylic acid, AS）对乙氧基钛[Ti(OEt)4]进行改性，以调控其水解与缩聚反应速率，进而制备有机-无机杂化材料。为表征该杂化材料的结构与形貌，并探究有机官能团对溶胶-凝胶法制备的TiO2杂化材料的影响，本研究采用了多种测试表征手段，包括傅里叶变换红外光谱（Fourier transform infrared spectroscopy）、核磁共振波谱（NMR）、扫描电子显微镜（SEM）、热重分析（thermogravimetric analysis）及X射线衍射（X-ray diffraction）。
