Unveiling the photocorrosion mechanism of zinc oxide photocatalyst: Interplay between surface corrosion and regeneration

Evaluation of zinc sulfide heterostructures as catalysts for the transformation of CO2 into valuable chemicals and clean energy generation

“…Further studies conducted by Weide et al 131 delineated the photocorrosion pathway under oxygen-free conditions, revealing the production of various compounds, including elemental Zn and S, ZnSO 4 , and Zn(OH) 2 , with a significant hydrogen to Notably, the presence of oxygen significantly accelerates photocorrosion, with ZnSO 4 being the primary corrosion product in oxygenated environments, highlighting the complex dynamics of photocatalytic reactions involving ZnS. 132 To mitigate these degradation processes, contemporary advancements in materials science have introduced ZnSbased heterostructures and composites. Coating ZnS with protective layers of inert materials, such as graphene or titanium dioxide, has proven effective in shielding the catalyst from degradative environmental factors.…”
