摘要：
Mn-doped CeO2 nanorods have been prepared from CeO2 particles through a facile composite-hydroxide-mediated (CHM) approach. The analysis from X-ray photoelectron spectroscopy indicates that the manganese doped in CeO2 exists as Mn2+. The magnetic measurement of the Mn-doped CeO2 nanorods exhibits an enhanced ferromagnetic property at room temperature with a remanence magnetization (Mr) of 1.36 x 10(-3) emu/g and coercivity (Hc) of 22 Oe. Comparative UV-visible spectra reveal the shift of the absorption peak of the CeO2 from ultraviolet region to visible light region after being doped with Mn. The room temperature ferromagnetic properties and light absorption of the Mn-doped CeO2 nanorods would have potential applications in photocatalysis and building of photovoltaic devices.
