In this paper, LaPO4 nanorods have been successfully synthesized via a simple water-ethyleneglycol (H2O-EG) mixed-solvothermal route, employing lanthanum nitrate (La(NO3)(3).xH(2)O) as a La3+ ion source and monobasic sodium phosphate (NaH2PO4.2H(2)O) as a PO43- ion source. The as-obtained products were characterized by means of X-ray powder diffraction (XRD), energy dispersive spectrometry (EDS), (high resolution) transmission electron microscopy (HR/TEM), selected area electron diffraction (SAED) and field emission scanning electron microscopy (FESEM). Some factors influencing the formation of LaPO4 nanorods, including the reaction temperature, the volume ratio of water/EG and the original amount of H2PO4- ions, were investigated. Experiments showed that the volume ratio of water/EG and the original amount of H2PO4- ions could markedly affect the morphology of the final product. (C) 2011 Elsevier Inc. All rights reserved.
