Rational design and fabrication of MoSx nanoclusters decorated Mn0.3Cd0.7S nanorods with promoted interfacial charge transfer toward robust photocatalytic H2 generation

Bo Wang et al.

Summary: In this work, a novel MoSx/Mn0.3Cd0.7S composite catalyst with 1D nanostructure was successfully designed and fabricated. The intimate interface between MoSx nanoclusters and Mn0.3Cd0.7S nanorods achieved through in situ photoreduction route contributes to high-efficiency interfacial charge separation. The resulting catalyst exhibits dramatically enhanced visible-light-driven photocatalytic H2 production activity due to more efficient spatial charge separation and enriched active sites.

Surface modification of CuInS2 photocathodes with ruthenium co-catalysts for efficient solar water splitting

Sang Youn Chae et al.

Summary: In this study, the photoelectrochemical activity of CuInS2 photocathodes was investigated after sequential surface modification with a-MoSx, Pt, or Ru. The results showed that a Ru-modified CuInS2/a-MoSx photocathode exhibited higher photoelectrochemical activities compared to a Pt-modified one. The high activity of the Ru modification was found to be due to the more suitable energy level of Ru on the photocathode, which improved the electron transfer and carrier lifetime during photoelectrochemical reaction.

Photodeposition of molybdenum sulfide on MTiO3 (M: Ba, Sr) perovskites for photocatalytic hydrogen evolution

Talha Kuru et al.

Summary: Photocatalytic hydrogen evolution using semiconductor materials to convert solar energy into chemical energy has been effectively studied. Perovskite-based materials have been widely used as semiconductor catalysts for this purpose. In this study, molybdenum sulfide photodeposited onto MTiO3 (M: Ba, Sr) perovskites (MTiO3/MoSx) was investigated for photocatalytic hydrogen evolution under solar light irradiation in the presence of triethanolamine and eosin Y. The results showed that BaTiO3/MoSx and SrTiO3/MoSx exhibited significant improvement in hydrogen production efficiency and stability compared to pristine MTiO3. The photocatalytic hydrogen activity followed the order of SrTiO3/MoSx > BaTiO3/MoSx > MoSx > SrTiO3 > BaTiO3. Additionally, SrTiO3/MoSx demonstrated higher hydrogen activity than SrTiO3/Pt due to the presence of active sites created by MoSx on the catalyst surface.

Amorphous MoSx electro-synthesized in alkaline electrolyte for superior hydrogen evolution

Chunxia Niu et al.

Summary: Amorphous MoSx electrocatalysts have gained significant attention due to their structural flexibility and rich defects, providing abundant active sites for hydrogen evolution. In this study, amorphous MoSx films were electrochemically deposited on carbon cloth via constant potentials method in a deposition solution containing different amounts of (NH4)2MoS4 and NaOH. The resulting samples exhibited amorphous structure as confirmed by X-ray diffraction patterns, while X-ray photoelectron and Raman spectrum revealed the presence of defective MoV=O sites coordinated with bridged sulfur. The optimized MoSx electrode showed remarkable overpotentials for hydrogen evolution reaction (HER) in both acidic and alkaline electrolytes, surpassing the performance of most amorphous MoSx-based electrodes. The proposed catalytic pathway suggests the active role of MoV=O sites. This synthesis approach in alkaline electrolyte holds potential for the preparation of high-performance electrocatalysts for HER.
