Bimetallic defect-engineered CoMoMOF modulates CdZnS for efficient hydrogen production from water/microplastic waste
Summary
Researchers created a novel photocatalyst combining metal-defect-engineered materials to simultaneously generate hydrogen fuel and break down PET plastic waste using light energy. The system produced significantly more hydrogen using PET microplastics as a feedstock compared to water alone, suggesting plastic waste could serve as a raw material for clean energy production. This "waste to fuel" approach could address both the plastic pollution crisis and the energy transition, though it remains at an early laboratory stage.
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 H 2 , which is twice as much as the defect-free sample, and 258.9 µmol using PET microplastics.
