Inspired by the scanning probe block copolymer lithog. process, hollow silica shells were loaded with polymer-metal ink mixtures and investigated as solution-based nanoreactors for the synthesis of gold nanoparticles. The incorporation of poly(ethylene oxide) (PEO) into these hollow silica nanoreactors (approx. 40 nm in size) and the use of a two-step reductive annealing process (first at 200¡ãC and then at 600¡ãC) results in a high yield (76%) of larger (?6 nm) single nanoparticles; when the polymer is not used, smaller (?3 nm) particles dominate, and the yield of single particles is only 6%. It was determined that particle coarsening mostly occurs in the temperature range where the polymer is present and not degraded (i.e., <400¡ãC for PEO), as indicted by correlative in situ scanning/transmission electron microscopy in a reductive gas-phase environment. Thus, polymer incorporation in this nanoreactor system, which is amenable to scale up, drives the complete conversion of nanoreactor contents without excessive metal loss, highlighting the impact of nanoreactor composition and structural design on particle synthesis.
