제목 Photocatalytic H2 Evolution Coupled with Degradation of Plastic
초록 The recycling of plastics has aroused people's concern because the “white pollution” not only pollutes the environment but also is a waste of resources. Hydrogen (H2) energy is an ideal and ultimate sustainable clean energy, which can be easily liberated from water splitting. Herein, a series of MoS2/CdxZn1−xS photocatalysts with uniform 2D/2D structure are reported for solar water–reductive H2 products coupled with the degradation of polyethylene terephthalate (PET) plastic. The MoS2/Cd0.5Zn0.5S heterojunction with a loading mass of 4.3 wt% MoS2 exhibits the best H2 evolution rate of 15.90 mmol g−1 h−1 in an aqueous solution due to its appropriate redox ability, great light absorption, and carrier separation abilities. Then, the oxidation products of PET are analyzed by 1H-NMR spectroscopy, which demonstrates the PET being efficiently degraded to molecule compounds, such as formate and acetate. The work provides a feasible solution to the problem of plastic pollution and meets the demand for sustainable clean energy simultaneously.
