Wang, Wei; Heggen, Marc; Cui, Wei; Probst, Benjamin; Alberto, Roger; Cui, Chunhua (2020). Synergizing hole accumulation and transfer on composite Ni/CoOx for photoelectrochemical water oxidation. Chemical Communications, 56(70):10179-10182.
Ni/CoOx sites were supported on an around 2 nm-TiOx modified hematite photoanode for water oxidation. TiOx demonstrates insignificant hole accumulation and a catalytically inactive surface that serves as an ideal platform. We reveal that the NiOx favors the extraction of holes from the TiOx surface, which are efficiently transferred to active CoOx for water oxidation.
