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.

“…Photoelectrochemistry is an ideal method for generating hydrogen because it uses solar energy and produces no pollutants in the process.

[2][3][4][5][6] Photocatalyst can absorb solar energy to produce electron hole pairs, which can turn light energy into photoelectrochemical energy, while photogenerated electrons can split water to produce hydrogen.…”

Constructing 1D/2D heterojunction photocatalyst from FeSe ₂ nanorods and MoSe ₂ nanoplates with high photocatalytic and photoelectrochemical performance

Although the traditional metal oxide catalyst has high activity and strong degradation ability, the forbidden bandgap is generally larger, and the utilization rate of sunlight is much low. Moreover, the high internal resistance inhibits carrier transfer, so the photoelectrochemical performance needs to be improved. Selenides with narrow bandgap and low internal resistance are promising candidates for photocatalysts. A new type of 1D/2D selenide heterojunction was constructed by compositing MoSe 2 and FeSe 2 , two kinds of narrow bandgap metal selenides. In this 1D/2D heterojunction, MoSe 2 presents a three-dimensional network structure, which can effectively collect and transport optical carriers, and it is an ideal heterostructure as a substrate loaded with 1D FeSe 2 nanorods. Moreover, this heterojunction has good light absorption characteristics and can achieve full spectrum absorption of ultraviolet and visible light. This FeSe 2 /MoSe 2 composite has photocatalytic performance more than 3.4 times that of MoSe 2 , and its photoelectrochemical performance is more than 2 times. The experimental results show that FeSe 2 / MoSe 2 is an ideal composite system with great potential in photocatalysis.

Recently, various kinds of methods have been implemented to broaden the visible light response and fasten the carrier's separation of TiO2‐based photoanodes. As a promising hydrogen evolution reaction catalyst, MoSe2 is rarely investigated especially combined with TiO2 photoanode. In this study, we report a composite photoanode of MoSe2 nanosheets (with 1T and 2H phase)‐modified 3D TiO2 nanoflowers (NFs).The hybrid of 3D TiO2 NFs/2D MoSe2 holds great promise in boosting the PEC water splitting performance. TiO2 NFs/MoSe2‐15 showed the largest photocurrent density of 1.40 mA/cm2, which was five times higher than that of pure TiO2 NFs under AM1.5G illumination. Moreover 10 times improvement in current density was observed for the TiO2 NFs/MoSe2‐15 under visible light. This increase could be ascribed to synergistic effects of light absorption enhancement and more efficient carrier separation after MoSe2 modification. This study not only provides a reference to boost the photoelectrochemical performance of photoelectrodes but also renders a perspective on the potential applications of MoSe2 nanosheets.
