Single-crystal PbMoO4 nanorods with diameters of 70–80 nm and lengths of about 300–400 nm have been successfully obtained via a surfactant-free sonochemical method. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and electron diffraction (ED). It is found that the precursor played a key role in the preparation of PbMoO4 nanorods. PbMoO4 nanorods can be successfully obtained when PbCrO4 nanorods were used as precursor. Once PbCrO4 were replaced with Pb(NO3)2, PbMoO4 nanoparticles were formed. The synthesis mechanism was also discussed. It is rational to expect that some other one-dimensional metal molybdates may also be synthesized by this method.
