三维TiO2陶瓷网络的直写无模成型及结构设计对其光催化性能的调制作用
Preparation of 3D Ceramic Meshes by Direct-write Method and Modulation of Its Photocatalytic Properties by Structure Design
摘要
Abstract
3D meshes of TiO2 were fabricated by direct writing and subsequently sintered at 1150℃ for 2 h in an air atmosphere for photocatalytic degradation (PCD) of methylene blue(MB) solution.The crystal structure and morphology of the samples were determined by X-ray diffraction(XRD) and scanning electron microscope(SEM).PCD properties of the sintered meshes were obtained in an ultraviolet-visible light spectrophotometer,and were found to be better than that of cylindrical samples with the same weight.Three kinds of mesh structures were designed,sintered and measured.The results show that reasonable design could cause significant enhancement in the PCD activity by more than 60％.This enhancement could be attributed to irradiation absorption increment,which was caused by structure design of photocatalyst.关键词
