“…In such a system, it is expected that the less negative CB potential of In(OH) 3 , and the possibility of shared In ions (multiple interfaces with intimate contact), would facilitate spatial separation of charge carriers and thus improve photocatalytic performance. As expected, such nanocomposites with enhanced photocatalytic activity have been reported, including ZnIn 2 S 4 /In(OH) 3 [44][45][46], ZnIn 2 S 4 /In(OH) 3 /NiS [47], ZnIn 2 S 4 /In(OH) 3 /ZnWO 4 [48], and CdIn 2 S 4 /In(OH) 3 /Zn 2 GeO 4 [49].…”

The development of highly active and stable photocatalysts, an effective way to remediate environment pollution and alleviate energy shortages, remains a challenging issue. In this work, a CdIn2S4/In(OH)3 nanocomposite was deposited in-situ on NiCr-LDH nanosheets by a simple hydrothermal method, and the obtained CdIn2S4/In(OH)3/NiCr-LDH heterostructure photocatalysts with multiple intimate-contact interfaces exhibited better photocatalytic activity. The photocatalytic H2 evolution rate of CdIn2S4/In(OH)3/NiCr-LDH increased to 10.9 and 58.7 times that of the counterparts CdIn2S4 and NiCr-LDH, respectively. Moreover, the photocatalytic removal efficiency of Cr(VI) increased from 6% for NiCr-LDH and 75% for CdIn2S4 to 97% for CdIn2S4/In(OH)3/NiCr-LDH. The enhanced photocatalytic performance was attributed to the formation of multi-interfaces with strong interfacial interactions and staggered band alignments, which offered multiple pathways for carrier migration, thus promoting the separation efficiency of photo-excited electrons and holes. This study demonstrates a facile method to fabricate inexpensive and efficient heterostructure photocatalysts for solving environmental problems.

“…40 The SAED image in the inset picture of Figure 3e proved its polycrystalline nature rather than welldefined single crystal, and similar results were reported in previous articles. 38 Although the SEM results of ZIS@CIS-0.05 composite are identical with those of pure ZnIn 2 S 4 microspheres, the images of TEM and HRTEM are greatly different between them. For ZIS@CIS-0.05 composite, extrinsic species can be obviously observed on the surface of flowerlike microspheres.…”

“…In our recent report, it was found that ZnIn 2 S 4 @In(OH) 3 microspheres had a prominent photocatalytic H 2 production of 2088 μmol•g −1 due to the formation of core−shell-like structures. 38 Therefore, the synergetic effect of ZnIn 2 S 4 @CuInS 2 core−shell p−n junction on highly efficient photocatalytic H 2 production can be expected.…”

The efficient separation of photoexcited electrons and holes is crucial for improving the activity of photocatalytic hydrogen evolution. Herein, an efficient core−shell p−n heterojunction of ZnIn 2 S 4 @CuInS 2 microflowers has been devised and fabricated by two-step hydrothermal method. The results revealed that the marigold-like microspheres of ZnIn 2 S 4 @CuInS 2 heterojunction consisted of thin nanosheets, matched well in the lattice, and had a large interface contact area, which boosted charge separation and transfer for solar hydrogen production. Moreover, the intimate interfacial contact between n-type ZnIn 2 S 4 and p-type CuInS 2 resulted in the formation of unique p−n heterojunction, which further promoted charge separation due to the built-in electric field. As a consequence, the ZnIn 2 S 4 @CuInS 2 photocatalyst with 5 atom % CuInS 2 showed the highest production of H 2 evolution (about 1168 μmol•g −1 ) among all prepared photocatalysts, which was nearly 4-fold the amount of the hydrogen production for the pristine ZnIn 2 S 4 . Therefore, the core−shell p−n heterojunction is an efficient structure design for the utilization of solar energy to obtain clean energy.

“…Indium hydroxide (In(OH) 3 ), a pblock semiconductor with a widegap of 5.15 eV, has drawn increasing attention owing to its strong oxidation and reduction performance. Yu et al [240] fabricated a 2D/3D mosaic structure In(OH) 3 /ZnIn 2 S 4 binary heterojunction by attaching 2D In(OH) 3 cubic nanosheets on the surface of 3D ZnIn 2 S 4 flowerlike microsphere (Figure 16c) used for H 2 evolution. Zhao et al [241] also fabricated 2D/3D mosaic structure In(OH) 3 /ZnIn 2 S 4 hollow microspheres binary type II heterojunction used for photocatalytic H 2 production and methylene blue degradation.…”
