With the continuous growth of global energy demand and increasingly severe environmental issues, extensive utilization traditional fossil fuels has led to serious crises pollution problems. In this study, a hydrothermal method was employed, by adding ethanolamine controlling different temperatures, pink zinc sulfide with vacancies synthesized. UV-Vis DRS analysis indicated that sample exhibited significant visible light absorption characteristics within wavelength range 500–550 nm. The presence confirmed through XPS. Due existence vacancies, demonstrated excellent photocatalytic hydrogen evolution activity without need for co-catalysts, optimal achieving rate 7631.70 μmol h−1 g−1. Zinc can provide additional active sites, enhance catalytic efficiency, promote separation photogenerated electrons holes. Furthermore, introduction effectively reduces bandgap material, significantly broadening its range. This work provides new approach enhancing in pure ZnS offers novel strategies further design ZnS-related photocatalysts.

Abstract This review explores the versatile catalytic applications of molybdenum disulfide (MoS₂), emphasizing its significance in chemical transformations. Out various transition metal dichalcogenides (TMDs), MoS₂ has garnered considerable attention due to high surface area, tunable band gap, and unique electronic properties, which collectively contribute exceptional efficiency. Its layered structure, enriched with active edge sites, facilitates strong interactions enables diverse electrocatalysis, photocatalysis, cocatalysis. In demonstrates remarkable efficiency hydrogen evolution oxygen reduction reactions, enhanced activity stability achieved through nano‐structuring modifications. As a photocatalyst, ability optimize structures promote charge separation makes it highly effective for water splitting pollutant degradation. MoS 2 acts as an excellent cocatalyst enhance properties catalysts by modifying area adsorption, reactive species (ROS) production mechanism, microscopic process change sites. The recent advancements heterojunctions, nanocomposites, hybrid materials their performance are also highlighted.
