Abstract

Quantum-sized gold clusters are deposited on TiO₂ both as a photosensitizer and catalyst, and coupled to plasmonic gold nanoparticles as a light harvesting antenna. Photocurrent enhancement was observed for Au ₂₅(SG)₁₈ and Au₃₈(SG)₂₄ but not for Au₁₀₂(SG)₄₄ (SG = glutathione). The maximum enhancement factor of ∼9 is reached at 900 nm.
