Abstract	TiO2 nanoparticles with an exposed reactive {001} facet have exhibited more favourable properties in photocatalysts, batteries and photoelectrochemical cells owing to their superiority of association properties with adsorbents, electron transfer, ion insertion capacity, etc. to the conventional TiO2. We recently revealed the effects of {001} facet-dominating TiO2 on the electron injection from photo-excited dye-sensitizers exhibiting an order of magnitude increase in the rate constant. We herein report that {001} facet-dominating TiO2 enhances the efficiency of photocatalytic H2 evolution with the porphyrine dye-sensitized TiO2 nanoparticles in an aqueous suspension especially with the specific pH region above 8 (in alkaline solution) under visible irradiation as compared with conventional P25. The analysis of fluorescence quenching in a TiO2 colloidal suspension based on the Stern–Volmer relationship is employed to estimate the electron injection efficiency of photo-excited electrons in dye-sensitizers. The results imply that the enhancement of H2 evolution by {001} facet-dominating TiO2 is attributed to its efficient photo-excited electron injection process from dye-sensitizers to TiO2 as compared with conventional P25.
