Photocatalytic H2 Evolution

Hydrogen production over dye-sensitized Pt/P25 under visible-light irradiation was investigated by using methanol or TEOA as an electron donor. The binuclear Ru(II) dye (Ru2(bpy)4L1-PF6) shows the best photosensitization in both sacrificial reagent solutions due to its larger conjugation system and “antenna effect”, which is loosely linked with TiO2 and exhibits more steady and higher increases in H2 evolution upon prolonging the irradiation time in comparison with the tightly linked N719. The dynamic equilibrium between the linkage of ground dye and divorce of oxidized dye from TiO2 can enhance the electron injection and hinder the backward transfer, and then improve the H2 evolution efficiency.
