The kinetics and mechanism of photo-assisted Ag(I)-catalysed water oxidation with S2O82-

16 December, 2014 - 09:54

Dalton Trans., 2015, 44,710-717
DOI: 10.1039/C4DT02254H, PaperLihong Yu, Jidan Wang, Dan Guo, Wansheng You, Meiying Liu, Lancui Zhang, Can Li
It is reported that visible light ([small lambda] [greater-than-or-equal] 400 nm) can improve Ag(I)-catalyzed water oxidation into O2 with S2O82- remarkably. The photo-assistant results from the absorbance of the AgO+ species at 375 nm, promoting the rate-determining step (AgO+ + H2O [rightward arrow] Ag+ + H2O2). A reasonable mechanism has been proposed.
