【摘要】近些年随着工业化的发展,水体污染越来越成为一个严峻的环境问题。解决该问题的一个有效策略就是设计合成能够利用太阳光降解污染物的光催化剂。采用一种简单经济的静电纺丝工艺,结合不同温度下的煅烧,我们制备了一维BiYO3纳米纤维,其平均直径约为100nm。通过在可见光照射下对刚果红染料的吸附和光催化降解实验,考察了不同的煅烧温度对材料光催化活性的影响,结果表明煅烧温度为700℃时该材料对刚果红表现出最好的光催化活性。更多还原

【Abstract】 With the development of industrialization, waste water containing organic pollutants is becoming a serious problem. An effective method to solve such problem is to design and synthesize photocatalysts that can decompose pollutants by using sunlight. BiYO3 nanofibers werefabricated using a simple and economical electrospinning technique with subsequent calcination. The average diameter of the nanofibers was approximately 100 nm. The adsorption and degradation experiments of Congo red dye under visible light irradiation were carried out. We investigated the effect of calcination temperature on photocatalytic activity of the material. The results showed that the material exhibited good photocatalytic activity for Congo red when calcination temperature was 700 ℃.更多还原
