Recycling nanocatalysts by tuning solvent quality.
Catalytic surfactant stabilized gold-containing nanoparticles have been recovered by a new isothermal low-energy approach, by controlled and reversible changes in colloid stability based on fine-tuning of solvent quality. Once recovered, the nanoparticles can be re-dispersed in the solvent, or indeed dispersed into a different solvent. The morphology of the nanoparticles is not significantly affected by the recovery process and they can be used and reused as oxidation catalysts.
