In this Dalton Transactions Hot Article, Fenghua Chen and colleagues prepared multifunctional nanoparticles composed of a Fe3O4–Au nanocomposite core and a porous silica shell.
The aim of the synthesis was to maintain the magnetic and optical properties of the nanocomposite while ensuring stability.
The catalytic activity of the product was tested on reduction of o-nitroaniline to benzenediamine by NaBH4. The core/shell nanoparticles showed improved activity compared to Fe3O4–Au composite nanoparticles alone.
