Bimetallic defect-engineered CoMoMOF modulates CdZnS for efficient hydrogen production from water/microplastic waste
DOI: 10.1039/D5GC04815J, PaperHeyu Li, Lingjiao Li, Haiyu Wang, Zhiliang Jin
The type-I heterojunction of CZS with NaOH-treated V-CMM (Co/Mo vacancies) confines carriers and enhances redox. CZS/V-CMM-20% yields 1525 µmol H2, which is twice as much as the defect-free sample, and 258.9 µmol using PET microplastics.
