“…The performances of dye sensitized TiO 2 photocatalysts without co‐catalyst, and with Cu 2 WS 4 or Pt as co‐catalyst were evaluated and compared. The trend of H 2 evolution rates for both MC‐32 and MC‐048 was tested to be TiO 2 /Dye/Pt>TiO 2 /Dye/Cu 2 WS 4 >TiO 2 /Dye, Although Cu 2 WS 4 possessed lower activity than Pt, this study presented a good example for noble metal‐free DSP system for visible‐light‐driven H 2 evolution [46] …”

“…[45] Their group further synthesized two TPA-based dyes MC-32 and MC-048 ( Figure 17 and Table 1, No. [45][46] in the absence and presence of EDOT group as the π-bridge and used them to sensitize TiO 2 photocatalyst in combination with Cu 2 WS 4 or Pt as co-catalyst. Compared to MC-32, MC-048 showed increased molar extinction coefficient and red-shifted absorption band due to the extended π-conjugated structure caused by inserted EDOT group, meanwhile the HOMO level value of MC-048 was increased, resulting in a decreased oxidation potential.…”

“…Likewise, tungsten-and molybdenum-based ternary chalcogenides such as Cu 2 WS 4 [261][262][263], Cu 2 MoS 4 [264][265][266], and Ag 2 WS 4 [267] can also be used as the HER cocatalysts to promote hydrogen production. For example, using Cu 2 WS 4 as a noble metal-free cocatalyst for organic dyes, sensitized TiO 2 could double the solar-hydrogen production rate [268].…”

Semiconductor-based solar water splitting is regarded as one of the most promising technologies for clean hydrogen production. The rational design of semiconductor materials is critically important to achieve high solar-to-hydrogen (STH) conversion efficiencies towards practical applications. A rich family of tungsten-and molybdenum-based materials have been developed as both photocatalysts and cocatalysts for solar-hydrogen production in the past years, providing more opportunities to achieve high solar-to-hydrogen (STH) efficiencies. In this review article, we comprehensively review the recent progress of tungsten-and molybdenum-based materials for solar-hydrogen production. In particular, the strengths and drawbacks of each material system are critically discussed, followed by an overview of the emerging strategies to improve their performances. Finally, the key challenges and possible research directions of tungsten-and molybdenum-based materials are presented, which would provide useful information for the design of efficient semiconductor materials for solar-hydrogen production.

When it is asked, “where can refractory metals be used?,” the possible shortest answer is, “where cannot they be used?” The uses of refractory‐metal‐based compounds in research and industry are too many to be enumerated; nevertheless, some outstanding examples are briefly mentioned here. Essentially, chalcogenide forms of refractory metals are preferred in the fabrication of high‐performance structures. Therefore, expanding the current studies that usually focus on tungsten‐ and molybdenum‐based structures to other materials may open new opportunities. Moreover, research on ternary and quaternary structures can also be a keystone in creating high‐performance products. The rationale of the present review is to give a brief overview of the recent history of refractory‐metal‐based chalcogenides (RMCs). Initially, the framework is confined to the general design and approaches for the synthesis of refractory metal chalcogenides. The assay is continued by extending with characteristic features of materials from crystalline properties to thermoelectric attributes and examining device fabrication processes. Taken together, the device fabrication part where RMCs are mainly used is extensively focused upon. Finally, outlook and future perspectives are given on the design and construction of RMCs to enable future inspiration and innovation.
