“…The template method can be used to prepare ZIS‐based composites with hierarchical core–shell structures. A typical hard template synthetic method for the preparation of the hierarchical core–shell TiO 2 @ZIS hollow nanospheres was reported by Li et al [ 72 ] SiO 2 nanospheres were regarded as the template during the synthetic reaction. After the TiO 2 grows on its surface, the SiO 2 template was removed, and finally, the ZIS nanosheets were loaded to obtain hierarchical core–shell TiO 2 @ZIS hollow nanospheres.…”

“…Regarding the 2D ZIS nanosheets, many researchers have also found that assembling the ZIS nanosheets on substrate materials to form composite photocatalysts can not only prevent their aggregation, but also brings the advantages of heterojunctions. It has been reported that the ZIS nanosheets are loaded on substrate materials with different structures, such as nanorods, [62][63][64][65] nanowire, [66] nanocages, [67,68] nano/microtubes, [69,70] nanocube, [71] nano/microspheres, [72,73] etc. For example, Zhang et al prepared ZIS/CdS composite photocatalysts composed of CdS nanorods and 2D ZIS nanosheets for photocatalytic reduction of Cr(VI).…”

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.

“…Many efforts have been made over the past years to develop effective and low-cost non-noble electrocatalysts for HER [4,5]. To date, numerous nonnoble electrocatalysts, such as metal oxides [6][7][8][9], sulfides [10][11][12][13][14], selenides [15][16][17][18], phosphides [19][20][21][22], nitrides [23,24] and carbides [25][26][27] have been extensively explored. However, most non-noble metal-based catalysts, especially oxides, are unstable in acidic solution [28].…”

It is a great challenge to prepare non-noble metal electrocatalysts toward hydrogen evolution reaction (HER) with large current density. Synergistic electronic and morphological structures of the catalyst have been considered as an effective method to improve the catalytic performance, due to the enhanced intrinsic activity and enlarged accessible active sites. Herein, we present novel ternary Co 1−x V x P nanoneedle arrays with modulated electronic and morphological structures as an electrocatalyst for highly efficient HER in alkaline solution. The NF@Co 1−x V x P catalyst shows a remarkable catalytic ability with low overpotentials of 46 and 226 mV at current densities of 10 and 400 mA cm −2 , respectively, as well as a small Tafel slope and superior stability. Combining the experimental and computational study, the excellent catalytic performance was attributed to the improved physical and chemical properties (conductivity and surface activity), large active surface area, and fast reaction kinetics. Furthermore, the assembled Co-V based electrolyzer (NF@Co 1−x V x-HNNs(+)||NF@Co 1−x V x P(−)) delivers small full-cell voltages of 1.58, 1.75, and 1.92 V at 10, 100, and 300 mA cm −2 , respectively. Our findings provide a systematic understanding on the V-incorporation strategy to promote highly efficient ternary electrocatalysts via synergistic control of morphology and electronic structures.

Although lead halide perovskites are demonstrated to be promising photocatalysts for hydrogen evolution from hydrogen halide splitting, it still remains challenging to fabricate efficient and stable catalysts. Here MoS 2 nanoflowers with abundant active sites are assembled with methylammonium lead iodide (MAPbI 3 ) microcrystals to form a new heterostructure. Its hydrogen evolution rate can reach up to about 30 000 μmol g −1 h −1 , which is more than 1000-fold higher than pristine MAPbI 3 under visible light irradiation (λ ≥ 420 nm). Importantly, the solar HI splitting efficiency reaches 7.35%, one of the highest efficiencies so far. The introduction of MoS 2 with proper band alignment and unsaturated species can efficiently promote the charge separation and afford more active sites for H 2 production. This finding not only provides a highly efficient and stable photocatalyst for hydrogen evolution but also offers a useful modification strategy on lead halide perovskites.
