Harnessing ZnCrO/g-CN nanosheet heterojunction for enhanced photocatalytic degradation of rhodamine B and ciprofloxacin.

Utilizing semiconductors for photocatalytic processes in water bodies as an approach to environmental remediation has gained considerable attention. Theoretical band position calculations revealed a type-II step-scheme charge flow mechanism for ZnCrO/g-CN (ZCr/gCN), emphasizing effective heterojunction formation due to synergies between the materials. A composite of agglomerated nanoparticle ZnCrO (Zinc chromium oxide - ZCr)/g-CN (graphitic carbon nitride - gCN) nanosheets was synthesized using the ultrasonication and leveraging the heterojunction to enhance degradation efficiency and active sites participation.
