The aforementioned photo-oxidation of sulfur aniones can eventually lead
to disruption of the ZnS crystals and release of Zn2+ ions that could not be
completely prevented even by efficient hole scavengers [271]. In the context of
primordial photochemistry, such a photocorrosion would have led to the continuous
rejuvenation of the ZnS surfaces and the formation of fresh (photo)catalytic
interfaces. In addition, photocorrosion would have continuously released Zn2+
ions, keeping their concentration at the illuminated ZnS surfaces high.
