Effect of CdS loading on the properties and photocatalytic activity of MoS nanosheets.

Molybdenum sulfide (MoS) and modified MoS with different percentages of CdS (10%, 30%, and 50% CdS@MoS) were successfully synthesized and characterized. The photocatalytic performance of the MoS and CdS@MoS was evaluated by degrading brilliant green (BG), methylene blue (MB), and rhodamine B (RhB) dyes under visible light irradiation. Amongst the synthesized photocatalysts, 50% CdS@MoS exhibited the highest photocatalytic activity, degrading 97.

Microwave-assisted synthesis of ZnS@CuInS for photocatalytic degradation of coloured and non-coloured pollutants.

Copper indium sulfide (CuInS) exhibits strong visible light absorption and thus has the potential for good photocatalytic activity; however, rapid charge recombination limits its practical usage. An intriguing strategy to overcome this issue is to couple CuInS with another semiconductor to form a heterojunction, which can improve the charge carrier separation and, hence, enhance the photocatalytic activity. In this study, photocatalysts comprising CuInS with a secondary CuS phase (termed CuInS) and CuInS loaded with ZnS (termed ZnS@CuInS) were synthesized via a microwave-assisted method.

Recent development of metal oxides and chalcogenides as antimicrobial agents.

Pathogenic microbes are a major concern in hospitals and other healthcare facilities because they affect the proper performance of medical devices, surgical devices, etc. Due to the antimicrobial resistance or multidrug resistance, combatting these microbial infections has grown to be a significant research area in science and medicine as well as a critical health concern. Antibiotic resistance is where microbes acquire and innately exhibit resistance to antimicrobial agents.

Recent Progress of Metal-Organic Frameworks and Metal-Organic Frameworks-Based Heterostructures as Photocatalysts.

In the field of photocatalysis, metal-organic frameworks (MOFs) have drawn a lot of attention.

Molybdenum Disulfide-Based Nanomaterials for Visible-Light-Induced Photocatalysis.

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.

Role of Anions in the Synthesis and Crystal Growth of Selected Semiconductors.

The ideal methods for the preparation of semiconductors should be reproducible and possess the ability to control the morphology of the particles with monodispersity yields. Apart from that, it is also crucial to synthesize a large quantity of desired materials with good control of size, shape, morphology, crystallinity, composition, and surface chemistry at a reasonably low production cost. Metal oxides and chalcogenides with various morphologies and crystal structures have been obtained using different anion metal precursors (and/or different sulfur sources for chalcogenides in particular) through typical synthesis methods.
