Experimental study demonstrates one-pot radiolytic reduction for synthesizing hybrid Ta2O5@PDA/Au nanocomposites, suggesting an efficient alternative to conventional multi-stage methods.
Hybrid Ta2O5/Au nanoparticles (NPs) were synthesized by in situ radiolytic reduction of Au ions in tantalum oxide hydrosol. For efficient Au binding, Ta2O5 NPs were preliminarily modified with a polydopamine (PDA) coating. This one-pot approach allows the monodispersed Au NPs to be directly anchored on the Ta2O5@PDA surface, which compares favourably with conventional multi-stage method for creation such structures.
