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.…”

“…However, in comparison with other highly efficient photocatalysts, MgInS 4 remains unsatisfactory owing to its relatively high photogenerated electron and hole recombination efficiency and must be modified to achieve high photocatalytic performance. 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.…”

Preparation of Novel Layered High Entropy Bismuth-Based Materials and their Photocatalytic Degradation Mechanism

“…Subsequently, the corresponding band structures of BiO­[ClBrI­(CO 3 ) 0.5 ] can be determined (Figure S5). Since the conduction potential of BiO­[ClBrI­(CO 3 ) 0.5 ] was greater than the reduction potential of O 2 /•O 2 – (−0.33 V vs NHE), , the photoelectrons of BiO­[ClBrI­(CO 3 ) 0.5 ] possess the ability to trap the formation of molecular oxygen •O 2 – . However, the valence potential of BiO­[ClBrI­(CO 3 ) 0.5 ] was smaller than the reoxidation potential of OH – /•OH (+2.38 V vs NHE) .…”
