Nickel hybrid nanoparticle decorating on alumina nanoparticle cluster for synergistic catalysis of methane dry reforming

A gas-phase controlled synthesis method is demonstrated to prepare Ni-CeO2 nanocrystallites decorating on Al2O3 nanoparticle clusters (NPC) for synergistic catalysis of dry reforming of methane with CO2 (DRM). The method combines the principles of aerosol-phase evaporation-induced self-assembly with...

Zusammenfassung:A gas-phase controlled synthesis method is demonstrated to prepare Ni-CeO2 nanocrystallites decorating on Al2O3 nanoparticle clusters (NPC) for synergistic catalysis of dry reforming of methane with CO2 (DRM). The method combines the principles of aerosol-phase evaporation-induced self-assembly with colloid-phase stabilization of Al2O3 nanoparticles in sprayed aqueous droplets. Hybrid NPC was successfully created with ultrafine Ni crystallites (
