white crystalline powder
Verwenden
Tetraoctylammonium bromide (TOAB) has been used as a phase transfer agent to transfer gold tetrachloroaurate from aqueous phase to organic phase in a two-phase (organic-aqueous) method of alkanethiol stabilized gold nanoparticle synthesis. It is also used to prepare TOAB-capped gold nanoparticles, which shows well-defined plasmon absorption compared to thiol-capped nanoparticles.
Allgemeine Beschreibung
Tetraoctylammonium bromide is an organic surface coating agent commonly used to control the size and shape during nanoparticle synthesis.
