摘要/Abstract

摘要： 介绍了一种基于光敏特性陶瓷浆料的浆料直写无模三维成型技术制备的线条直径为270 μm微米的TiO₂木堆结构光降解器件. 我们对光敏浆料的配制方法、浆料直写无模成型的工艺原理进行了研究; 利用TEM和 XRD表征光敏浆料中TiO₂粉体的形貌和物相; 对器件的光降解性能进行了分析与测试; 利用光学显微镜和SEM对成型后的样品结构、尺寸及表面微观形貌进行了分析, 并基于此分析给出了这种器件高催化效率的原因 . 实验结果显示, 该器件具有完整的三维木堆结构, 表面粗糙多孔, 极大地增加了光催化的作用面积, 从而使其具有较高的光降解效率. 在紫外光照射10分钟 min后, 初始浓度为4mg/L的亚甲基蓝溶液降解率达到76%, 紫外光照射20min后, 亚甲基蓝溶液降解率可达91%.

Abstract: A kind of photo sensitive ceramic inks is was developed for Direct-WriteAssembly (DWA).A TiO₂based photolysisdevice of wood pile structure whose with filament diameter of is around 270 μm was fabricated through this method. The preparation of the photo sensitive ink and the principle of the DWA were investigated in order to obtain ink with proper rheology. XRD and TEM were used to characterize the phase and morphology of the TiO₂ powder in the ink. Optics microscope is was appliedto analyze the internal architecture and typical size of the wood pile structure. The sample immersed in methylene-blue solution is was radiated under UV-light for 20 min and the transmittance of the solution measured byUV-Vis spectrophotometer. Under the UV-light irradiation for 10minutes, ,the degradation rate of methylene blue solution with initial concentration of4mg/L is was 76%, and then increases increased to91% fora 20 minutes’ after UV radiation for 20 min. We also use SEM was usedto study the filament surface morphology of the woodpile and investigatethe enhancement mechanism of the high photolysis performance based on these results.The effective photolysis performance can be attributed to the 3D woodpilestructure with rough porous surface, which greatly increases the area of the photocatalysisreaction.
