The plausible role of carbonate in photo-catalytic water oxidation processes.


DFT calculations point out that the photo-oxidation of water on GaN is energetically considerably facilitated by adsorbed carbonate. As the redox potential of the couple CO3(˙-)/CO3(2-) is considerably lower than that of the couple OH˙/OH(-) but still enables the oxidation of water it is suggested that carbonate should be considered as a catalyst/co… (More)
