Abstract
Polycrystal nanowires of orthorhombic PbCl2, with diameter of 20-30 nm, len gth up to tens microns, and cell constants of a=0.454 nm, b=0. 763 nm, c=0, 904 nm, were synthesized by micelle template of polyoxyethylene(9)-dodecyl -ether(C12E9) , n-pentanal and cyclohexane when the molar ratio of water to C12E9, R, is 10, the volume ratio of cyclohexane to C12E9 is 8, c(C12E9) i s 0.18 mol/L. and the concentration of c (Pb2+) and c(Cl-) are 0.1 mol/L. T he middle process and an intermediate were captured. On the basis , the for mation mechanism of PbCl2 nanowires were studied. The results indicated tha t the formation of PbCl2 nanowires was probably via the mechanism of the di rectional aggregation and orientated growth of the PbCl2 colloidal particle s.
