3D MoS2/MgIn2S4 Nanoflower Heterojunctions for Photoreduction of Cr(VI): Mechanism, Influence, and Toxicity Evaluation

“…For In 3d (Figure d), the two peaks at 445.05 and 453.57 eV were attributed to In 3d 5/2 and In 3d 3/2 of In 3+ , respectively. The two S 2p peaks of MS belonged to S 2p 3/2 and S 2p 1/2 , respectively (Figure e), indicating that S in MS was present in the form of S. − MIS and the 3% MS/MIS generally showed similar spectra, except for the peak of Mo. For Mo 3d (Figure f), the XPS peaks of Mo in MS can be divided into three core-level XPS peaks.…”

“…The construction of semiconductor heterojunctions with other semiconductors having suitable band gaps is a well-documented and effective method to facilitate photogenerated carrier migration, with MgIn 2 S 4 @In 2 O 3 , , MgIn 2 S 4 /oxygen-doped g-C 3 N 4 , and MgIn 2 S 4 /Bi 2 WO 6 being examples. Heterojunction construction effectively contributes to photocatalytic efficiency, especially the construction of S-scheme heterojunctions, affording an interesting method to solve the problem of rapid carrier recombination and inadequate redox ability, influenced by the interior electric field and band bending. , Owing to the merits of S-scheme heterojunctions, the photocatalytic decoration of MgIn 2 S 4 can effectively accelerate charge separation and transition while maintaining a strong e – /h + reduction/oxidation ability in composite materials. This synergistic effect endows MgIn 2 S 4 composites with substantial photocatalytic activity.…”

Photocatalysis Meets Piezoelectricity in a Type-I Oxygen Vacancy-Rich BaTiO3/BiOBr Heterojunction: Mechanism Insights from Characterizations to DFT Calculations

“…Architecting heterojunctions is one of the most popular strategies to addressing this issue. Nowadays, various BiOBr-based heterojunctions have been architected with other semiconductor materials to inhibit e – –h + pair recombination and achieve high-efficiency photodegradation of organic pollutants, including S-scheme (BaFe 12 O 19 /BiOBr and P-doped g-C 3 N 4 /BiOBr), Z-scheme (Cu 2 ZnSnS 4 /BiOBr), type-II (BiOBr@ZnIn 2 S 4 and BiOBr/Bi 3 O 4 Br), and p-n (BiOBr/α-Bi 2 O 3 and BiOBr/ZnO) heterojunctions. In a heterojunction, the mismatched Fermi levels of the distinct semiconductors can promote spatial separation of the photogenerated e – –h + pairs at their contact interfaces.…”
