Light-induced surface defects in anodic TiO 2 nanotubes as trapping centers for single Pt atoms, a co-catalyst for enhanced photocatalytic hydrogen evolution

The amorphous nature of TiO 2 nanotubes (TNT) enables the formation of air-stable light-induced surface defects, facilitating reactive Pt SAs deposition. When crystallized, these TNT with surface-anchored Pt SA reach a significant H 2 production rate.
