Implication

Single-molecule fluorescence imaging reveals preferential catalytic reduction on {101} facets in anatase TiO2, indicating that face-specific electron trapping dictates reaction efficiency.

Key Points

To resolve the inherent photocatalytic activity across distinct crystal facets of anatase titanium dioxide using single-molecule and single-particle fluorescence techniques.
Monitored catalytic reduction reactions at solid/solution interfaces of anatase TiO2 particles in real time using redox-responsive fluorogenic dye probes.
Conducted single-molecule imaging and kinetic analyses of fluorescent reaction products to map and quantify active sites across {101} and {001} crystal facets.
Catalytic reaction sites for probe molecule reduction were preferentially localized on crystal {101} facets rather than on {001} facets with higher surface energy.
Kinetic differences revealed that facet-specific electron-trapping probability governs reaction site preference over thermodynamic surface energy alone.
