    摘要:

    采用靜電紡絲技術(shù)，以硫酸鈦、聚乙烯吡咯烷酮、DMF和水為原料，制備出柔性TiO2納米纖維。用XRD、SEM、TEM和TG-DTA等分析手段對(duì)納米纖維進(jìn)行表征。結(jié)果表明，所得產(chǎn)物為多晶結(jié)構(gòu)柔性TiO2納米纖維，平均直徑約為100 nm，長(zhǎng)度>300 μm。以甲基橙、羅丹明B和苯酚為降解物，考察了焙燒溫度對(duì)光催化效果的影響，柔性TiO2納米纖維對(duì)這3種降解物均可達(dá)到較高的降解率。對(duì)柔性TiO2納米纖維的形成機(jī)制進(jìn)行了討論

    Abstract:

    Flexible TiO2 nanofibres were fabricated by electrospinning with Ti(SO4)2, polyvinyl pyrrolidone (PVP), dimethyl formamide(DMF) and deionized water as starting materials. The samples were characterized with XRD, FESEM, TEM and TG-DTA. The results reveal that the obtained TiO2 nanofibres are flexible and polycrystalline structure. The mean diameter of the TiO2 nanofibres is about 100 nm, and the length is greater than 300 μm. The influence of calcination temperatures on the photocatalytic effect for TiO2 nanofibres was investigated through methyl orange, rhodamine-B and phenol as degradation compounds. The photocatalytic experiments results indicate that flexible TiO2 nanofibres possess high degradation rates for these three degradation compounds. The formation mechanism of the flexible TiO2 nanofibres was also discussed
