Does this paper clarify how holes are able to react with "free" hydroxyl anions to form "free" hydroxyl radicals? I'm having trouble understanding it.

The authors are suggesting that the hydroxyl formation is due to interfacial transfer. See attached.
The authors claim that these are surface processes. So the hole is generated in the bulk, migrates to the surface and then ...
An explanation of the role of holes in forming free hydroxyl radicals is given.
