摘要:
以PVP为载体,乙酸锌(Zn(CH3COO)2·2H2O)和硝酸银(AgNO3)为原料,采用静电纺丝与煅烧相结合的方法制备了一系列银掺杂量不同的ZnO复合纳米材料.用SEM、FTIR、XRD对煅烧前后的纤维形貌和结构进行表征.以刚果红为目标降解物,考察了煅烧温度和Ag掺杂量对Ag/ZnO复合纳米纤维的光催化活性的影响.结果显示,煅烧温度和Ag掺杂量对复合纳米材料的催化活性影响显著,600 ℃煅烧3 h制得的Ag掺杂摩尔分数为6%的Ag/ZnO复合纳米材料,经155 W紫外灯照射210 min后对40 mg·L-1刚果红溶液降解率可达99%以上.催化剂重复利用4次后对刚果红的催化降解率仍可保持在94%以上.
Abstract:
A series of ZnO doped with different amounts of Ag nanocomposite materials were fabricated by using PVP as a carrier,adding silver nitrate and zinc acetate as raw material via electrospinning technique combined with the calcination.The morphology and structure of Ag/ZnO were characterized by scanning electron microscopy(SEM),fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD).Congo red dye was used as pollutant models,the UV lamp as the light source,to explore the effects of calcination temperature and silver doped amounts on photocatalytic activity of the composite materials.The results show that Ag-6%-doped ZnO obtained at 600 ℃ for 3 h has the best photolytic efficiency for Congo red.The degradation of 40 mg·L-1 Congo red solution could reach up to 99% under 155 W UV light exposure for 210 min.the degradation rate remains above 94% after being reused for 4 times.
