Investigation of precursors' reduction speeds. a Schematic illustration of the formation process of AuRu3 alloy NPs with fcc and hcp crystal structures. (RAu and RRu are the reduction speed of the Au and Ru precursors, respectively.) b, c The change in UV–vis spectra of b HAuBr4 and c K2Ru(NO)Cl5 in EG with reaction time. d, e The change in UV–vis spectra of d HAuBr4 and e RuCl3 with CTAB in DEG with reaction time. The inset pictures in (b), (c), (d) and (e) are the samples which were taken at different times
