Abstract

Abstract As a typical member of sulfide family, ZnIn2S4 bears impressive activity in photocatalysis. Nonetheless, egregious recombination of photo-excited electron and hole pairs confines its practical usage. In this study, PCN-224, a metal organic framework (MOF) composed of porphyrin linkers and Zr clusters, is employed to establish a novel hierarchical structured ZnIn2S4@PCN-224 via a solvothermal method. These as-prepared composites are further evaluated by visible-light-driven photocatalysis and able to present steady performance. The optimized ZnIn2S4@PCN-224 has a hydrogen production rate of 0.284 mmol h−1 in absence of Pt, higher than many contrastive ZnIn2S4-based photocatalysts even in assistance of Pt cocatalyst. Besides, it is able to dominate the degradation of tetracycline hydrochloride (TCH), giving 99.9 % pollutant removal within 60 min, about 4.7 times higher than that catalyzed by ZnIn2S4. It is supposed that the great improvement in photocatalysis is ascribable to the establishment of Z-scheme junction between ZnIn2S4 and PCN-224.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
