Compact Integration of TiO₂ Nanoparticles into the Cross-Points of 3D Vertically Stacked Ag Nanowires for Plasmon-Enhanced Photocatalysis.

ABSTRACT: The compact integration of semiconductor TiO₂ nanoparticles (NPs) into the 3D crossed region of stacked plasmonic Ag nanowires (NWs) enhanced the photocatalytic activities through synergistic effects between the strong localized surface plasmon resonance (LSPR) excitation at the 3D cross-points of the Ag NWs and the efficient hot electron transfer at the interface between the Ag NWs and the TiO₂ NPs. This paper explored new hybrid nanostructures based on the selective assembly of TiO₂ NPs onto 3D cross-points of vertically stacked Ag NWs. The assembled TiO₂ NPs directly contacted the 3D Ag NWs; therefore, charge separation occurred efficiently at the interface between the Ag NWs and the TiO₂ NPs. The composite nanomaterials exhibited high extinction across the ultraviolet-visible range, re
