“…With the CC modification, it is impressive to see that the ZnIn 2 S 4 nanosheets can be explicitly and evenly grown on such small carbon dots (Figures 2d and e) rather than interspersed together. [22] Therefore, a strong chemical interaction is present between CC and ZnIn 2 S 4 . Such a structure of CC/ZnIn 2 S 4 could guarantee sufficient contact between CC and ZnIn 2 S 4 nanosheets, which is capable to expedite the migration of charge carriers.…”

Cellulose-derived carbon (CC) dot-directed growth of ZnIn 2 S 4 was achieved through hydrothermal treatment of carboxylated cellulose followed by in situ growth of ZnIn 2 S 4 nanosheets. The carbon dots inherited from carboxylated cellulose equip plenty of surface carboxyl groups, which induce the ionic interaction with Zn 2 + and In 3 + and the guided growth of ZnIn 2 S 4 . As a result, the nanosheets of ZnIn 2 S 4 are evenly and intimately grown on the small carbon dots, providing high-speed channels for charges transfer. In conjunction with the reinforced visible-light capture and good conductivity of carbon dots, the resultant CC/ZnIn 2 S 4 shows an outstanding photocatalytic activity. As a proof-of-concept, visible-light-driven 5hydroxymethylfurfural oxidation into 2,5-diformylfuran was conducted. The evolution of 2,5-diformylfuran over the optimal CC/ZnIn 2 S 4 sample can reach ~2980 μmol g À 1 , about 3.4 times that of pristine ZnIn 2 S 4 . Additionally, the apparent quantum yield could attain 3.4 % at a wavelength of 400 nm.

“…To this end, Kong and coworkers reported the 3D hierarchical microarchitecture of Z‐scheme photocatalyst consisting of UiO‐66(COOH) 2 and ZnIn 2 S 4 decorated with non‐noble MoS 2 cocatalyst ( Figure ). [ 80 ] The total bandgap energy of UiO‐66(COOH) 2 is 3.62 eV and ZnIn 2 S 4 is 2.64 eV; the energy levels of VB and CB of the two components perfectly match with the Z‐scheme system. The UiO‐66(COOH) 2 /ZnIn 2 S 4 decorated with MoS 2 photocatalyst, therefore, improves the charge transfer within UiO‐66(COOH) 2 and ZnIn 2 S 4 .…”

Various photocatalysts have been developed for photocatalytic water splitting—one of the most important processes that produces dihydrogen as clean energy for fuel cells. The successful achievements for this application are based mainly on transition metal oxides and some metal sulfides/nitrides. Recently, metal–organic frameworks (MOFs), a class of hybrid functional materials comprising organic backbone tethered infinitively in limitless way by metal‐oxide clusters, both of which can be customized accurately at the molecular level for targeted applications, have been able to photocatalytically degrade water. Herein, it is first aimed to comprehensively review fundamentals of water splitting catalyzed by semiconductor photocatalysts, which casts light on understanding of challenges in this area, thus providing strategies for development, if not rational design, of visible‐light‐driven MOFs that are capable of degrading water to hydrogen and oxygen. The recent advancements of using MOF photocatalysts for water splitting are further described in a way that benchmark achievements and limitations are considered so that the readers can imagine the big picture in this field and pay considerable attention to future solutions.

“…The synthesis of MOF-derived materials requires an organic solvent environment. This excellent composite material composed of ZIS and MOFs, such as UiO-66, [28,94,95] UiO-66-(COOH) 2 , [96] NH 2 -UiO-66, [97] MIL-125(Ti), [98] and NH 2 -MIL-125(Ti), [99,100] has been prepared through the solvothermal method. For example, Peng et al prepared the novel nanostructured UiO-66@ZIS photocatalysts by coating ZIS nanosheets on UiO-66 nanospheres by a simple solvothermal method, and the samples synthesized by this method had uniform structures and improved photocatalytic activity for hydrogen production under visible light illumination, as shown in Figure 9.…”

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.
