| Abstract: | 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. |
| Keywords: | low-temperature hydrothermal process CeO2 nano-rods UV-shielding |
