摘要:
为了提高太阳光的光催化效率,以二水合乙酸锌、六水合硝酸钴为原料,以竹纤维为模板,采用浸渍-热转化制备了钴掺杂摩尔分数为0%~4.0%的Co/ZnO复合材料.利用X-射线衍射、扫描电镜、热重分析对复合材料的结构、形貌和物相等进行表征.在太阳光的照射下,使用亚甲基蓝评价复合材料的光催化活性,探究前驱物煅烧时间及钴掺杂量对Co/ZnO催化剂光催化性能的影响.结果表明:当钴掺杂摩尔分数为2.0%时,浸泡2 h获得的前驱物经过600 ℃煅烧2 h制成的Co/ZnO复合材料对亚甲基蓝的降解效率最佳,降解率为91.29
Abstract:
In order to improve the photocatalytic efficency of sunlight,Co-doped ZnO composites with different Co doping concentrations(0%~4.0% mole fraction)are prepared by immersion-thermal conversion method,using two zinc acetate hydrate and six cobalt nitrate hydrate as raw materials and bamboo fibers as template.The prepared Co/ZnO composites are characterized by X-ray diffraction analysis(XRD),scanning electron microscopy(SEM)and thermogravimetric analysis(TG).The effects of calcining time of precursor and Co doping content on the photocatalytic activity of Co/ZnO composites are investigated under sunlight.The results show that the Co/ZnO composite with 2.0% Co addition prepared by immersing the precursors for 2 h at 600 ℃ for 2 h have the best photocatalytic effect on the degradation of methylene blue,and the degradation rate is 91.29%.Co doping can increase the photocatalytic speed and degradation rate of zinc oxide.
