Engineered Pd-Ga alloy nanoparticles through spark ablation and in-flight metal-organic precursor decomposition
Pd-Ga alloy nanoparticles with tunable compositions were produced by combining spark ablation with a downstream injection of a metal-organic precursor. This dual-process approach enables control over nanoparticle composition and morphology by adjusting precursor flow rate and sintering temperature. At lower precursor flows, uniform Pd-Ga nanoparticles form, exhibiting stable Pd5Ga2 and Pd2Ga phase
