Subject:
air flow; carbon monoxide; gold; nanocomposites; nanoparticles; oxidation; surface plasmon resonance; titanium dioxide
Abstract:
... Ultrafine Au particles incorporating TiO₂ heterodimers were synthesized using an ambient heterogeneous spark discharge and the resultant materials were employed both in oxidizing photocatalytically CO gas and killing photothermally cancerous cells. Ti–Au spark configuration was employed to vaporize Ti and Au components into an airflow and finally ultrafine Au particles (∼2 nm in lateral dimension) ...

Abstract:
... The gas-phase self-assembly of reduced graphene oxide (rGO) nanoflakes with highly ordered ultrafine titania (TiO₂) particles was performed and the resultant hybrid material displayed an enhanced photocatalytic performance, both in producing hydrogen and in degrading dyes. Freshly synthesized TiO₂ nanoparticles (∼35 nm in equivalent mobility diameter) were quantitatively incorporated with nanoscal ...
