A novel pathway toward efficient improvement of the photocatalytic activity and stability of CdS-based photocatalyst for light driven H2 evolution: The synergistic effect between CdS and SrWO4

Facile fabrication of a flexible and shape-adaptive Cd0.5Zn0.5S-based photocatalytic system and its photocatalytic activity for hydrogen evolution from water

“…21,22 Alternatively, our previous results indicated that SrWO 4 is an excellent co-catalyst for CdS. 23 Our preliminary experimental results also showed that the Cd x Zn 1− x S/SrWO 4 nanocomposite possesses satisfactory photocatalytic activity for H 2 evolution, where the Cd 0.5 Zn 0.5 S/SrWO 4 nanocomposite exhibits the highest photocatalytic activity. Based on the above-mentioned results, we speculate that an efficient, flexible and shape-adaptive Cd x Zn 1− x S-based photocatalytic system can be fabricated by loading the Cd 0.5 Zn 0.5 S/SrWO 4 nanocomposite on FP.…”

Photocatalytic Membranes Toward Practical Environmental Remediation: Fundamental, Fabrication, and Application

“…Qian et al prepared carbon quantum dots (CQDs) decorated Bi 2 WO 6 by wet-impregnation to degrade gaseous volatile organic compounds (VOCs), which expanded the absorption spec-trum to the visible region. [21] Sulfides used as photocatalysts include CdS, [22] ZnS, [23] CuInS 2 , [24] Cu 2 ZnSnS 4 , [25] etc. Chen et al successfully synthesized immobilized TiO 2 nanoribbons decorated with Au and CuS nanoparticles, and the Au-CuS-TiO 2 N-Bromosuccinimide significantly prevents the recombination of photogenic carriers and makes more effective use of the solar spectrum.…”

Fluorinated-TiO2/Mn0.2Cd0.8S S-Scheme Heterojunction with Rich Sulfur Vacancies for Photocatalytic Hydrogen Production

“…At present, metal sulfides are frequently employed in photocatalytic hydrogen generation. For example, CdS with a suitable band gap and conduction band position has become a much studied photocatalyst. − Compared to traditional CdS materials, the Mn x Cd 1– x S solid solution material (MCS) not only exhibits good light corrosion resistance but also shows excellent performance in hydrogen production, attributed to the tunable band gap structure of solid solution sulfides. , Nevertheless, pure MCS still has inherent shortcomings, which include the rapid recombination of photogenerated electrons and holes and low-efficiency charge transfer, which restrict the potential future application in practice of this material. To date, several methods have been employed to enhance the photocatalytic activity of MCS, such as cocatalyst addition, heterojunction structure construction, loading precious metals (Ag, Pt), and defect engineering. , Among them, defect engineering is one of the most effective means of improving the surface activity centers of catalysts.…”
