Synthesis of hybrid Ta<sub>2</sub>O<sub>5</sub>@PDA/Au nanocomposites
Hybrid Ta<sub>2</sub>O<sub>5</sub>/Au nanoparticles (NPs) were synthesized by <em>in situ</em> radiolytic reduction of Au ions in tantalum oxide hydrosol. For efficient Au binding, Ta<sub>2</sub>O<sub>5 </sub>NPs were preliminarily modified with a polydopamine (PDA) coating. This one-pot approach allows the monodispersed Au NPs to be directly anchored on the Ta<sub>2</sub>O<sub>5</sub>@PDA surface, which compares favourably with conventional multi-stage method for creation such structures.
