分别利用钛酸异丙酯和四氯化钛水溶液,采用水热合成法制备了锐钛矿型的球状氧化钛(Ti O2)纳米溶胶及Ti O2纳米棒。采用不同质量配比共混得到电流体动力学技术(EHD)用溶胶,利用EHD技术在涂有Ti O2致密膜的导电玻璃基体上成膜,成功制备Ti O2纳米棒多孔光阳极复合薄膜。薄膜存在纳米至亚微米尺寸的多级孔道。 Anatase titania nanospheres and Ti O2 nanorods were prepared by hydrothermal synthesis using isopropyl titanate and aqueous solution of titanium tetrachloride. The electrohydrodynamics (EHD) sol was prepared by blending with different mass ratios, and the film was formed on the conductive glass substrate coated with Ti O2 dense film by EHD technique. The Ti O2 nanorods porous photoanode composite films were successfully prepared. Membranes exist in nanoscale to sub-micron size multistage pores.
