Overview

Colloidal synthesis achieved fine size control of gold nanoparticles in water, indicating potential for nanocatalysts.

Key Points

  • Fine size control of gold nanoparticles was achieved using only NaBH4 and HAuCl4 in water.
  • The method allowed for nanoparticles to be produced in the size range of 5-20 nm, indicating practical size tuning.
  • Stable colloidal dispersions with a volume scalability of 50 times were created, simplifying application in various fields.
  • The active nanocatalysts demonstrate effectiveness for water treatment and energy conversion applications.
