Laser ablation synthesis of metal-doped gold clusters from composites of gold nanoparticles with metal organic frameworks

Abstract Metal-doped gold clusters, mainly cages, are receiving rapidly increasing attention due to their tunable catalytic properties. Their synthesis is mostly based on complex procedures, including several steps. In this work, via adsorption of gold nanoparticles (AuNPs) from aqueous solution to...
