Large-scale synthesis of metal nanoclusters with thermal shocks

Researchers report significant advances in developing a high-temperature, fast nanomanufacturing technique for the large-scale production of ultra small metal nanoclusters decorated in a graphene host matrix. The size and morphology of the metal nanoclusters can be controlled by varying the reaction temperature and the mass loading of metal salt in the graphene aerosol nanoreactors. This one-step continuous aerosol-based thermal shock technique offers considerable potential for the manufacturing of well-dispersed and uniform nanoclusters stabilized within a host matrix.
