| 摘 要： | 摘译 近年来,作为一种高能量带隙半导体,二氧化钛(TiO2)由于在紫外光照射下具有良好的光催化活性,已引起科研人员的广泛关注.由于TiO2无色透明,具有广泛的应用前景,如薄的TiO2涂层可用于创建自清洁、防雾、超亲水表面.同时,也能用于太阳能电池等光电子行业.
化学溶液沉积法因具有相对简单的大面积生产工艺,且较低的制膜成本和高可用性,成为TiO2薄膜制备常用的方法之一.针对另一种TiO2制备方法,即溶胶凝胶法,大量研究文献主要关注乙醇的水解控制.然而,工业需求鼓励开发水基前驱设计.其难度在于钛醇盐与水的高反应性.在有机介质中,加入少量的水往往导致水解.因此,需要采用络合剂作为稳定剂,阻止纯水中的水解反应和避免由此产生的产物沉淀.

| Abstract: | In this work,aqueous chemical solution deposition route suited for inkjet printing is used for the synthesis of photocatalytically active TiO2 coatings.Environmentally friendly precursor solutions with electromagnetic ink-jet printing,allows cheap and simple processing of TiO2 films on glass.The hydrolysis reaction of water sensitive titanium alkoxide（Tialkoxide） precursor is controlled by adding complexing agents as citric acid and triethanolamine prior to water addition,and aqueous stable solutions are achieved.The pH of the solutions is brought to neutral to guarantee flexible processing,avoid damage to substrates and equipment.Solution parameters are adapted to obtain optimal gelation conditions and good jettability. The influence of processing parameters on the phase formation and surface morphology is studied by thermogravimetric analysis and differential thermal analysis（TGA/DTA）,X-ray diffraction（XRD）,scanning electron microscopy（SEM） and atomic force microscopy（AFM）.The photocatalytic activity of the films is evaluated by the degradation of methyl orange. |
