The results indicated that approximately spherical CdS particles about 5.1 nm, which has a cubic zinc blende structure with a cell constant a =0.581 8 nm, could be formed after the bean sprouts were successively soaked in 0 1 mol·L -1 Na 2S and 0 1 mol·L -1 CdCl 2 for 24 h. In addition, the tentative research for the reaction mechanism has been carried out. [WT5HZ]展开更多
Polycrystal nanowires of orthorhombic PbCl 2, with diameter of 20—30 nm, length 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)...Polycrystal nanowires of orthorhombic PbCl 2, with diameter of 20—30 nm, length 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(C 12E 9), n pentanol and cyclohexane when the molar ratio of water to C 12E 9, R, is 10, the volume ratio of cyclohexane to C 12E 9 is 8, c(C 12E 9) is 0.18 mol/L and the concentration of c(Pb 2+) and c(Cl-) are 0.1 mol/L.The middle process and an intermediate were captured. On the basis, the formation mechanism of PbCl 2 nanowires were studied. The results indicated that the formation of PbCl 2 nanowires was probably via the mechanism of the directional aggregation and orientated growth of the PbCl 2 colloidal particles.展开更多
