摘要
用钛酸四丁酯、聚乙烯吡咯烷酮和石墨相氮化碳(g-C_(3)N_(4))为前驱体,利用静电纺丝技术结合煅烧法,制备了具有可见光响应能力的g-C_(3)N_(4)/TiO_(2)复合纤维。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-可见光谱(UV-Vis)对样品的微结构和形貌进行表征。结果表明:g-C_(3)N_(4)纳米微粒均匀地负载在锐钛矿型的TiO_(2)纤维表面,光吸收带边扩展至460nm附近。考察了g-C_(3)N_(4)/TiO_(2)复合纤维在模拟太阳光降解罗丹明B的光催化性能,该复合材料是TiO_(2)纤维的2.26倍。
Combing the electrispining technology and calcination,the visible-light-response g-C_(3)N_(4)/TiO_(2) composite fibers were successfully synthesized based on tetrabutyl titanate,polyvinyl pyrrolidone and graphite carbon nitride(g-C_(3)N_(4)).The fibers were characterized by XRD,SEM and UV-visible spectroscopy to analyze the nanostructure and morphology.The results showed that g-C_(3)N_(4) nanopaticles were equably located on the surface of anatase TiO_(2) fiber,and the optical absorption bands of the fibers appeared at about 460 nm.Under visible light irradiation,the degradation rate of Rhodamine B though the fibers was 2.26 times compared with TiO_(2) fibers.
