4, 4′-((CH3) 3C) 2-2, 2′-bipyridine and dcb is 4, 4′-(CO2H) 2-2, 2′-bipyridine,
abbreviated TiO2| Ru, were investigated in acetonitrile electrolytes that contained 0.1 M
Na+, Li+, Mg2+, or Ca2+ perchlorate solutions with the electron donor tri p-tolylamine
(TPTA) or phenothiazine (PTZ). Pulsed 532 nm light excitation of TiO2| Ru with> 25 mM
donor concentrations quantitatively yielded TiO2 (e–)| Ru+ D+, and the corresponding …
