dc.description.abstractWe here report on the synthesis of metal/carbon nanohybrids by means of a laser ablation technique and a wet chemical method. Initially, metal/carbon nanohybrids were produced by laser irradiation of selected coordination compounds, leading to the synthesis of spongy-like nanostructured metal/carbon foams, which consist of metal nanoparticles embedded within amorphous carbon nanoparticles, amorphous carbon nanoparticles, and carbon domains exhibiting a higher graphitic order. The composition, metal nanoparticle dilution and crystallite size, and structure of these nanohybrid foams can be tailored by suitably tuning the laser parameters used and by choosing the metals and ligands of the irradiated coordinations compounds. These laser ablation method also enables the synthesis of metal-free carbon foams from aromatic molecular precursors. The study of the physicochemical properties and the design of processing strategies of the produced nanostructured carbon foams enable evaluating their potential technological applications. Thus, remarkable magnetic- and electrochemical properties have been demonstrated for these laser produced carbon nanomaterials. Physicochemical characterization also reveals that the produced nanostructured carbon foams are low density mesoporous materials with relatively low specific surface areas and thermally stable in air up to around 600ºC. Moreover, nanostructured carbon foam soots disperse well in a variety of solvents and can be successfully chemically processed therefore enabling their handling. Alternatively, wet chemistry strategies have been developed for the gold nanoparticle decoration of metal-free carbon foams. These gold/carbon nanohybrids provided an outstanding performance when tested as catalysts for the hydroamination of alkynes, leading to similar conversion values to those achieved using higher surface area carbon supports.-
