| Abstract |
Ultra-dispersed bimetallic nanomaterials have attracted much attention in the reduction of highly toxic aromatic nitro compounds to aromatic amines owing to their high stability, superior activity, reusability, and unique optical and electronic properties, as compared to monometalic nanocrystals. However, the lack of facile strategy of producing highly pure ultra-dispersed bimetallic nanocatalysts limits their practical industrial applications. Considering the above obstacles, we present a simple and effective strategy for the formation of bimetallic (PdCu) nanocrystals by liquid phase pulsed laser ablation using a bulk Pd metal plate submerged in CuCl2 solution with different concentrations. The microstructural and optical properties of the synthesized nanocrystals indicate that the obtained bimetallic nanostructures are highly pure and monodispersed. Moreover, bimetallic PdCu nanostructures show a higher catalytic activity than monometallic Pd nanocrystals for the hydrogenation of 4-nitrophenol to 4-aminophenol at room temperature, also exhibiting high stability for up to 4 recycles. Finally, we believe that the presented strategy and utilization of bimetallic nanocrystals for catalytic applications enable the development of novel bimetallic nanostructures produced by liquid phase pulsed laser ablation and their catalytic application for environmental remediation. |
