摘要

In this paper, we present a facile method for production stable aqueous dispersion of ferrocene (FO) nanoparticles. Ferrocene compounds were employed to achieve stable nanodispersions, stabilized with three different biopolymers namely, alginate, CM-dextran and chitosan. The nanoparticles produce are spherical, less than 10 nm in mean diameter and highly stable without any sedimentation. Fourier infrared transform (FTIR) and X-ray diffraction (XRD) studies confirmed the purity of ferrocene nanoparticles there is no modifications occur during the preparation route. FTIR spectra results were consistent with the presence of absorption band of cyclopentadienyl ring (C_5H_5- ion) which assigned to ν(C-C) vibrations (1409 cm~(-1)), δ(C-H) stretching at 1001 cm~(-1) and π(C-H) vibrations at 812 cm~(-1). Furthermore, all functional group for biopolymers such as C=O from carboxyl group of CM-dextran and sodium alginate appears at 1712 cm~(-1) and 1709 cm~(-1) respectively, indicating there are steric repulsion interactions for particles stabilization. Powder X-ray diffraction patterns of sedimented samples of the biopolymers-stabilized ferrocene (FO) showed all reflections which were indexed respectively to the {-110}, {001}, {-201}, {-111}, {200}, {-211}, {210}, {120} and {111} according to the monoclinic phase ferrocene. This confirmed that the products obtained were of high purity of Fe and EDAX analysis also suggests that the presence of the Fe element in the colloidal dispersion.
