Synthesis of Stable Aluminum Nanoparticles at Varying Reactant Concentrations and Their Surface-Enhanced Raman Scattering Activity.

ABSTRACT: Aluminum nanoparticles (Al NPs) were synthesized via catalyzed thermal reduction of an aluminum precursor in the presence of a capping ligand. A systematic study was conducted to examine the effect of dilution on nanoparticle synthesis by varying the volume of anhydrous toluene across four dilution factors while maintaining constant molar quantities of the aluminum precursor, catalyst, and ligand. This methodology is relevant for scale-up processes, where more dilute conditions can mitigate nanoparticle reactivity and enhance safety. The resulting Al NPs were characterized with respect to the yield, size distribution, chemical composition (bulk and surface), and morphology. Consistent and favorable yields were observed across all of the dilution conditions. The synthesized Al NPs were furt
