• AuPd-NPs are biofabricated using aqueous leaf extract of Delonix regia.
• Characterization of AuPd-NPs is done with UV–visible, DLS, TEM, XRD, EDX and FTIR.
• Nearly spherical, crystalline AuPd-NPs are fabricated within size range of 3-31 nm.
• AuPd-NPs shows recyclable catalytic efficiency towards the reduction of 3-NA.
• Catalytic efficiency of AuPd-NPs remained at about 93% even after 5 cycles.
The room temperature biofabrication of AuPd-NPs using aqueous leaf extract of Delonix regia was reported. The nature, morphology and size of nanoparticles were analyzed using UV–visible spectroscopy, DLS, XRD, TEM and EDX techniques. Nearly spherical crystalline AuPd-NPs were synthesized within size range of 3–31 nm. Appearance of broad intense reflection at 39.29° position, nearer to the mean of Pd (40.26°) and Au (38.37°) reflections suggested fabrication of AuPd-NPs. Furthermore, as-formed AuPd-NPs showed recyclable catalytic efficiency towards the reduction of 3-nitroaniline and it remained at about 93% even after recycling for 5 consecutive cycles in terms of normalized activity parameter.
