采用水热法以羧甲基纤维素钠(CMC)为晶体生长调节剂,在乙酸锌和CMC摩尔比为50∶3下合成菜花头与花形混合形貌的ZnO,通过X射线衍射(XRD)、扫描电子显微镜(SEM)、紫外-可见分光光度计(UV-Vis spectroscopy)等方法对ZnO进行表征。结果表明,合成的ZnO晶体结构良好,在紫外光照射下,ZnO具有优良的光催化降解苯酚活性,当ZnO用量为0.10g时光催化降解效果最好。
Hydrothermal method was used to synthesize ZnO with cauliflower head and flower-like morphology with carboxymethylcellulose sodium (CMC) as crystal growth regulator at the molar ratio of zinc acetate to CMC of 50: 3. The XRD, , Scanning electron microscopy (SEM), UV-Vis spectroscopy (UV-Vis spectroscopy) and other methods for the characterization of ZnO. The results show that the synthesized ZnO crystal has a good structure. Under ultraviolet light irradiation, ZnO has excellent photocatalytic activity for phenol degradation. When the amount of ZnO is 0.10g, the photocatalytic degradation is the best.
