Utilization of plasmonics in charge generation and separation by resonant energy transfer is well synergized with Schottky junction for enhanced photocatalytic water splitting.

A surfactant-free nanofabrication approach has been developed to confine dense Au nanoparticles in N-doped TiO₂ bowl-like nanoarrays, achieving full-spectrum photocatalysis.

The design achieves H₂ production rates of 637 μmol g⁻¹ h⁻¹ in full spectrum and 132 μmol g⁻¹ h⁻¹ in visible region, respectively, from pure water based on TiO₂.

This work represents a step towards large-scale photocatalyst fabrication and full-spectrum photocatalysis.
