Abstract

Herein, a microfluidic biosynthesis of Au–Ag bimetallic nanoparticle (NP) in a tubular microreactor, based on simultaneous reduction of HAuCl₄ and AgNO₃ precursors in the presence of Cacumen Platycladi (C. Platycladi) extract was studied. The flow velocity profile was numerically analyzed with computational fluid dynamics. Au–Ag bimetallic NPs with Ag/Au molar ratios of 1:1 and 2:1 were synthesized, respectively. The alloy formation, morphology, structure, and size were investigated by UV–Vis spectra analysis, transmission electron microscopy (TEM), high resolution TEM, scanning TEM, and energy-dispersive X-ray analysis. In addition, the effects of volumetric flow rate, reaction temperature, and concentration of C. Platycladi extract and NaOH on the properties of the as-synthesized Au–Ag bimetallic NPs were investigated. The results indicated that these factors could not only affect the molar ratios of the two elements in the Au–Ag bimetallic NPs, but also affect particle size which can be adjusted from 3.3 to 5.6 nm. The process was very rapid and green, since a microreactor was employed with no additional synthetic reagents used. This work is anticipated to provide useful parameters for continuous-flow biosynthesis of bimetallic NPs in microreactors.
