以自制Ti(OH)4、TiO2和NaOH为前驱物,经过超声混合后,通过水热反应法合成了不同Ti/Na比的钛酸钠光催化剂,并采用X-射线粉末衍射(XRD)和紫外-可见漫反射光谱(UV-vis-DRS)分别对合成的样品进行了晶型形貌和光吸收特性的表征并对其进行比较.实验结果表明:由于是水热反应,样品晶型较为复杂,可能在合成过程中形成了水合阳离子,导致它的晶型受到一定的影响.同时水热反应法合成的样品(Na2 Ti3 O7)对光的吸收带位置在337 nm左右.

@@@@Ti(OH)4、TiO2 and NaOH as precursor, after ultrasound mixed, through the hydrothermal reaction to synthesize titanate photocatalysts of different Ti/Na ratio.And using X-ray powder diffraction (XRD), UV diffuse reflectance spectroscopy (UV—DRS) to characterize the optical absorption properties and the crystal morphology of the titanate photocatalysts.Comparative experimental results show:As a result of hydrothermal synthesis , the crys-tal form of the samples was very complex .Maybe it formed hydratedcation in the synthetic process , resulting in a certain impact on its crystalline form.And the optical absorption band of samples (Na2 Ti3 O7 )by means of hydro-thermal reaction was about 337 nm.
