Plasmonic Pt nanoparticles-TiO₂ hierarchical nano-architecture as a visible light photocatalyst for water splitting.

ABSTRACT: Visible light-driven water splitting (VLWS) into hydrogen and oxygen is attractive and depends on efficient photocatalysts. Herein, we demonstrate the first exploration of the capability to control the morphology of nanostructured TiO₂ in conjunction with the choice of a suitable plasmonic metal (PM) to fabricate novel photocatalysts that are capable of harvesting visible light for more efficient VL-fuel conversion. This methodology affords us to successful access to the novel plasmonic Pt/TiO₂-HA (large Pt nanoparticles (NPs) supported on TiO₂ hierarchical nano-architecture (TiO₂-HA)) photocatalysts that exhibit plasmon absorption in the visible range and consequent outstanding activity and durability for VLWS. Particularly, the Pt/TiO₂
