A new photosensitive compound [Ru(bpy)2(TPAD)](PF6)2 (PS1) was synthesized.
PS1 was characterized by elemental analysis, 1H NMR, MS spectra, UV, PL and CV.
Photocatalyst PS1/0.5 wt% Pt/TiO2 was prepared and characterized by SEM and XRD.
The photocatalytic hydrogen-evolving conditions were optimized.
The total amount of hydrogen evolution reached to 9500 μmol·(g·catalyst)−1 within 5.5 h.
