| description | Silver/polyaniline (ag/pani) nanocomposites are promising materials due to
improved properties enabling various applications to date. In this work, a
comparative study on the citrate reduction of silver nanoparticles (agnps) was
carried out to investigate the combinations of trilithium citrate (tc) along with
ascorbic acid (aa) and d-sorbitol (ds) in reducing silver nitrate (sn). The influence
of varying concentrations of precursors, time, and temperature conditions towards
diffraction (xrd), ultraviolet/visible spectroscopy (uv-vis), transmission electron
microscopy (tem), and field emission scanning electron microscopy (fesem). The
characterization results showed that increasing concentrations of sn and aa yielded
increasing sizes of agnps, but vice versa for the addition concentrations of tc and
ds. The xrd patterns confirmed distinct peaks at approximately 20 = 38.2, 44.4,
64.6, 77.6, and 81.7°, representing bragg’s reflections from the (111), (200), (220),
(311), and (222) planes of the face-centred cubic lattice phase of metallic silver while
the uv-vis results recorded surface plasmon resonance in ranges of 414-452nm. |
