Se-vacancy engineered CoSe 2 /MoS 2 heterojunction with DFT revealed dual charge transfer pathways for accelerated antibiotic photocatalytic degradation

To address the challenge of antibiotic-contaminated water remediation, we designed a defect-engineered CoSe 2 @MoS 2 photocatalyst by integrating selenium-deficient CoSe 2 dodecahedra (derived from ZIF-67) with vertically aligned MoS 2 nanosheets.
