A novel photocatalytic system constructed using Eosin Y, alpha-Keggin-type diplatinum(II)-coordinated tungstophosphate Cs-3[alpha-PW11O39{cis-Pt(NH3)(2)}(2)]center dot 8H(2)O (Cs-Pt-1), alpha-Keggin-type mono-aluminum(III)-coordinated tungstosilicate K-5[alpha-SiW11{Al(OH2)}O-39]center dot 7H(2)O (K-Al-1), and titanium dioxide achieved a steady rate of hydrogen evolution with highly effective utilization of platinum sites from aqueous triethanolamine solution during a long-term visible light irradiation.
