“…The peak in the XRD diffractograms around 25°, unexpected for zinc blende crystals, has been found more often in the literature for a variety of zinc blende materials 25,42−44 and can be assigned to metal−ligand complexes on the surface of the QDs. 43,44 We remark that the InZnP QD cores showed a lattice parameter similar to bulk InP, suggesting only little Zn was incorporated. ICP-OES and XPS revealed that the In:Zn ratio (6:1) was indeed much lower than the feed fraction (2:1).…”

Indium phosphide quantum dots (QDs) have drawn attention as alternatives to cadmium- and lead-based QDs that are currently used as phosphors in lamps and displays. The main drawbacks of InP QDs are, in general, a lower photoluminescence quantum yield (PLQY), a decreased color purity, and poor chemical stability. In this research, we attempted to increase the PLQY and stability of indium phosphide QDs by developing lattice matched InP/MgSe core–shell nanoheterostructures. The choice of MgSe comes from the fact that, in theory, it has a near-perfect lattice match with InP, provided MgSe is grown in the zinc blende crystal structure, which can be achieved by alloying with zinc. To retain lattice matching, we used Zn in both the core and shell and we fabricated InZnP/Zn x Mg1–x Se core/shell QDs. To identify the most suitable conditions for the shell growth, we first developed a synthesis route to Zn x Mg1–x Se nanocrystals (NCs) wherein Mg is effectively incorporated. Our optimized procedure was employed for the successful growth of Zn x Mg1–x Se shells around In(Zn)P QDs. The corresponding core/shell systems exhibit PLQYs higher than those of the starting In(Zn)P QDs and, more importantly, a higher color purity upon increasing the Mg content. The results are discussed in the context of a reduced density of interface states upon using better lattice matched Zn x Mg1–x Se shells.

The photocatalyst CuS/CdIn 2 S 4 /ZnIn 2 S 4 with attractive visible light absorption was prepared by a microwave-assisted one-step method and then characterized by XRD, XPS, UV−vis/DRS, N 2 adsorption−desorption, SEM, TEM, and HRTEM tests. The results show that there are two kinds of crystal structures, hexagonal and cubic phase, in the product. Moreover, the composite has an absorption edge as high as 670 nm with a high visible light response. In addition, the composite possesses an excellent surface area of 239.3 m 2 /g, displays a favorable globular flower-like surface morphology, and consists mostly of three disparate shapes of crystals in the microstructure. Compared to heterogeneous ZnIn 2 S 4 and P25, as-prepared composite demonstrates the greatest photocatalytic activity under simulated sunlight and visible light by methyl orange degradation. Together with Pt loading as a cocatalyst, hydrogen was achieved over CuS/CdIn 2 S 4 /ZnIn 2 S 4 in Na 2 S−Na 2 SO 3 aqueous solution, leading to a hydrogen production rate of 358.4 μmol•h −1 •g −1 under simulated sunlight and a high hydrogen production rate of 233.9 μmol•h −1 •g −1 under visible light (λ > 420 nm). Additionally, the related formulas were utilized to calculate the semiconductor energy band configuration and speculate on the possible photoreaction mechanism of CuS/CdIn 2 S 4 /ZnIn 2 S 4 . Finally, the effect of multipathway photoinduced charge migration during photocatalysis process was explained.

Nowadays, photocatalytic technology is considered as one of the most efficient methods to solve the problem of the global energy shortage and the pollution of the environment. Among these outstanding photocatalysts, metal sulfide‐based semiconductors have attracted wide attention because of their good chemical stability, simple synthesis method, and relatively narrow bandgaps. ZnIn2S4 (ZIS), as a layered structure ternary metal chalcogenide and a rising material star, has made exciting breakthroughs in the past decades. Recently, studies have shown that a rich variety of ZIS composite nanostructures are developed. This review summarizes the recent advances and development in the design and improvement of ZIS and ZIS‐based photocatalysts in full‐spectrum photocatalytic applications. Furthermore, the applications of ZIS‐based photocatalysts are discussed, such as in photocatalytic hydrogen production, CO2 reduction, degradation of pollutants, and photocatalytic selective organic transformations under ultraviolett (UV), visible (Vis), and near‐infrared (NIR) light irradiation. In the end, a brief summary and perspectives on the challenges and future directions in the area of ZIS and ZIS‐based photocatalysts are also provided.
