Comment on "On the origin of multihole oxygen evolution in haematite photoanodes" [PDF]

open access: yes, 2023
The Article1 deals with the mechanism of oxygen evolution reaction (OER) on hematite photoanodes. The authors claimed that the OER rate or photocurrent density has a third-order (or power law) dependence on surface hole density.
