Monophasic ligand-free alloy nanoparticle synthesis determinants during pulsed laser ablation of bulk alloy and consolidated microparticles in water

Abstract: Chemical syntheses of homogenous solid solution alloy nanoparticles of noble metals require high temperature above 100 °C. Beside this, aqueous co-reduction methods lead to phase separation. In contrast, pulsed laser ablation in liquid (PLAL) allows synthesis of alloy nanoparticles with totally homogeneous ultrastructure in aqueous media at room temperature without reducing agents or organic ligands. However, to date, the dominant alloy formation process during PLAL is not fully understood. Based on the model … Show more

“…[14] But also ablation of apressed target consisting of powders of the constituent metals will lead to alloys such as PtAu, [15] NiMo [16] and AgAu. [15,17] The latter route not just leads to cheaper targets but also to time saving since series testing can be conducted by finely tuning the target and ultimately the nanoparticle composition. For instance,d ifferent catalysts for water oxidation as shown for NiFe LDH (layered double hydroxide) [18,19] or PtAu [15,20] alloy series for electrochemical reactions could be tested by using this route.…”

“…The research area of alloy nanoparticles [58][59][60] enables the usage of multifunctional nanoparticles with tunable properties based on their elemental compositions [59]. The targets used to prepare nanoparticles with the desired compositions can either be bought, if possible, or can easily be prepared from micropowder.…”

“…In case of the latter, micropowders of different elements are simply weighed in according to their desired ratio. Subsequently, the powders are mixed and pressed to yield a solid target [59]. However, mixing of different elements within particles on the nanoscale is not always possible, either for thermodynamic or kinetic reasons.…”
