Figure 8
Time evolution of (a) SAXS and (b) SANS 1D profiles during the in situ reduction process of a gold solution at 308 K. Insets show 2D (a) SAXS and (b) SANS patterns during hydroquinone synthesis of Au NPs. (c) Rod-like Au particle radius and length as a function of reaction time, as revealed from the SAXS data fitting. The inset in (c) is a TEM image of the Au particles, with average radius and length of about 8 and 60 nm, respectively; the scale bar is 100 nm. (d) The exponential volume fraction decay of the CTAB micelles with time, as obtained from SANS data fitting.
