Enhanced photocatalytic performance of SnS under visible light irradiation: strategies and future perspectives.

Tin(II) sulfide (SnS) has emerged as a promising candidate for visible light photocatalytic materials. As a member of the transition metal dichalcogenides (TMDs) family, SnS features a band gap of approximately 2.20 eV and a layered structure, rendering it suitable for visible light activation with a high specific surface area.

Advanced Strategies to Improve Performances of Molybdenum-Based Gas Sensors.

Molybdenum-based materials have been intensively investigated for high-performance gas sensor applications. Particularly, molybdenum oxides and dichalcogenides nanostructures have been widely examined due to their tunable structural and physicochemical properties that meet sensor requirements. These materials have good durability, are naturally abundant, low cost, and have facile preparation, allowing scalable fabrication to fulfill the growing demand of susceptible sensor devices.

Synthesis of iron(II,III) oxide/zinc oxide/copper(II) oxide (FeO/ZnO/CuO) nanocomposites and their photosonocatalytic property for organic dye removal.

A facile sol-gel method was adopted to synthesize iron(II,III) oxide/zinc oxide/copper(II) oxide (FeO/ZnO/CuO) nanocomposites with various CuO loadings at a low temperature. The prepared nanocomposites were characterized by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, UV-Vis spectroscopy, vibrating sample magnetometry, and Brunauer-Emmett-Teller (BET) surface area analyses. The photosonocatalytic properties of the nanocomposites were tested by methylene blue removal in aqueous solutions under the combination of UV or visible light and ultrasound.
