| 中文摘要: |
| 在低温水热条件下,通过一步法合成二氧化铈纳米杆.采用XRD、SEM和TEM对合成的样品进行表征,并利用紫外线可见光谱仪对氧化铈纳米杆的抗紫外线能力进行检测.实验结果表明:用醋酸铈和磷酸氢钠制备的氧化铈纳米杆形貌比较细长,平均直径～10 nm,平均长度～400 nm,且生长方向沿着<112>方向生长；另外,氧化铈纳米杆有很宽的吸收波段和很强的吸收能力,可作为理想的紫外线屏蔽材料. |
| 英文摘要: |
| CeO2 nano-rods are synthesized by the facile and efficient hydrothermal process in this experiment.The synthesized samples are characterized by using XRD,SEM and TEM,and the UV-shielding properties of CeO2 nano-rods are examined with an UV-vis spectrophotometer.The results show that morphology of the nano-rods synthesized by cerium acetate and sodium hydrogen phosphate is relatively slender,with an average diameter of ~ 10 nm,the average length of ~ 400 nm,and the growth direction is along the <112> direction.In addition,CeO2 nano-rods have a very broad absorption band and strong absorption capacity,so it can act as an efficient UV-shielding candidate. |
