Visible-light-responsive photocatalytic materials have a multitude of important applications, ranging from energy conversion and storage to industrial waste treatment. Molybdenum disulfide (MoS) and its variants exhibit high photocatalytic activity under irradiation by visible light as well as good stability and recyclability, which are desirable for all photocatalytic applications. MoS-based materials have been widely applied in various fields such as wastewater treatment, environmental remediation, and organic transformation reactions because of their excellent physicochemical properties. The present review focuses on the fundamental properties of MoS, recent developments and remaining challenges, and key strategies for tackling issues related to the utilization of MoS in photocatalysis. The application of MoS-based materials in visible-light-induced catalytic reactions for the treatment of diverse kinds of pollutants including industrial, environmental, pharmaceutical, and agricultural waste are also critically discussed. The review concludes by highlighting the prospects of MoS for use in various established and emerging areas of photocatalysis.

We report the results of a zinc oxide (ZnO) low-power microsensor for sub-ppm detection of NO and HS in air at 200 °C. NO emission is predominantly produced by the combustion processes of fossil fuels, while coal-fired power plants are the main emitter of HS. Fossil fuels (oil, natural gas, and coal) combined contained 74% of USA energy production in 2023.

With a rising interest in smart windows and optical displays, the utilization of metal oxides (MOs) has garnered significant attention owing to their high active sites, flexibility, and tunable electronic and optical properties. Despite these advantages, achieving precise tuning of optical properties in MOs-based quantum dots and their mass production remains a challenge. In this study, we present an easily scalable approach to generate WO quantum dots with diverse sizes through sequential insertion/exfoliation processes in solvents with suitable surface tension.
