Experimental and computational analysis of SnS encapsulated into carbonized chitosan as electrode material for potassium ion batteries.

Tin sulphide compounds (SnS, x = 1, 2) are potential anode materials for potassium-ion batteries (PIBs) due to their characteristic layered structure, high theoretical capacity, non-toxicity and low production cost. However, they suffer from significant volume changes resulting in poor performance of such anodes. In this work incorporation of SnS into the carbon structure was expected to overcome these disadvantages.

Synthesis and characterization of MoS-carbon based materials for enhanced energy storage applications.

The article delves into the synthesis and characterization of MoS-carbon-based materials, holding promise for applications in supercapacitors and ion batteries. The synthesis process entails the preparation of MoS and its carbon hybrids through exfoliation, hydrothermal treatment, and subsequent pyrolysis. Various analytical techniques were employed to comprehensively examine the structural, compositional, and morphological properties of the resulting materials.

Molybdenum sulfide modified with nickel or platinum nanoparticles as an effective catalyst for hydrogen evolution reaction.

In this study, we investigate the catalytic performance of molybdenum sulfide (MoS) modified with either nickel (Ni) or platinum (Pt) nanoparticles as catalysts for the hydrogen evolution reaction (HER). The MoS was prepared on the TiO nanotube substrates via a facile hydrothermal method, followed by the deposition by magnetron sputtering of Ni or Pt nanoparticles on the MoS surface. Structural and morphological characterization confirmed the successful incorporation of Ni or Pt nanoparticles onto the MoS support.

Scaling Up the Process of Titanium Dioxide Nanotube Synthesis and Its Effect on Photoelectrochemical Properties.

In this work, for the first time, the influence of scaling up the process of titanium dioxide nanotube (TiONT) synthesis on the photoelectrochemical properties of TiO nanotubes is presented. Titanium dioxide nanotubes were obtained on substrates of various sizes: 2 × 2, 4 × 4, 5 × 5, 6 × 6, and 8 × 8 cm. The electrode material was characterized using scanning electron microscopy as well as Raman and UV-vis spectroscopy in order to investigate their morphology, crystallinity, and absorbance ability, respectively.
