摘要：

We report a synthesis of two types of CeO2 nano-rods via the facile and efficient hydrothermal process free from any surfactant and template. The synthesized nano-rods are chemically identified as CeO2 with the standard fluorite structure but their morphologies are different. The nano-rods prepared with cerium nitrate hexahydrate and sodium phosphate are thicker and shorter with diameter of similar to 30 nm and length of similar to 100 nm, and those prepared with cerium acetate hydrate and dibasic sodium phosphate are thinner and longer with similar to 10 em in diameter and similar to 400 nm in length. Microstructural analyses reveal that the two species of nano-rods have low-energy {111} surfaces and grow along the < 112 > direction. As a consequence of their morphologies, the two types of synthesized nano-rods exhibit excellent UV-absorption ability in comparison to the irregular CeO2 nanoparticles.
