TL;DR: In this article , a simple ultra-sonication assisted approach, a series of Carrisa edulis fruit extract capped Co3O4 nanoparticles decorated on Montmorillonite K30 nanosheets were prepared.
Abstract: The in-depth usage of organic pollutants by pharmaceutical industries constitutes a major contaminant to the bodies of water due to their solubility, great mobility, ability to get attached to water bodies for a long period of time, and low biodegradability. Due to these, it may further cause disease and change the ecosystem of aqueous and other living organisms. Accordingly, effective removal of organic contaminants from waste water is a vital step in reducing the hazards. Photocatalysis is a potential technique for removing hazardous organic pollutants from wastewater. In this work, a simple ultra-sonication assisted approach, a series of Carrisa edulis fruit extract capped Co3O4 nanoparticles decorated on Montmorillonite K30 nanosheets (Co3O4/MK30) were prepared. The inherent physicochemical appearance and optical properties of as-prepared nanomaterials were investigated using a variety of analytical techniques. TEM analysis depicted the spherical shape of the Co3O4 NPs with the size of 11.25 nm. The degradation of methylthioninium chloride as a dye and tetracycline drug pollutants has been investigated in this study using individual and simultaneous photocatalysis systems in the presence of pure Co3O4 NPs and different ratios of Co3O4/MK30 nanocomposites. Owing to the generation of OH and O2 radicals, the 20% loaded Co3O4 on MK30 had the best photocatalytic performance of methylthioninium chloride (98.12%) and tetracycline degradation (87.4%), on exposing it to visible light. This research introduces a new design for MK30-based nanomaterials and proposes its use in environmental challenges.

TL;DR: In this article , various synthetic methods for preparation of catalysts based on montmorillonite for organic syntheses and assessing their catalytic activities are presented and compared with the original volume of the sample.
Abstract: Microscopic crystals with soft phyllosilicate group of minerals which formed through precipitation of water solution, are called montmorillonite (MMT). It is concentrated and transformed by natural weathering in environment caves and left aluminosilicates which were contained in the bedrock. By the adding water, montmorillonite swells and expanded considerably more than other clays. The amount of expansion is depended on the type of exchangeable cation contained in the sample. The presence of sodium as the predominant exchangeable cation, is increased the swelling several times rather original volume. Hence, Na-MMT used as the major constituent in nonexplosive agents for splitting rock in natural stone quarries. Advantageous properties of montmorillonite made it appropriate for many applications such as use in oil drilling industry as a component of drilling mud, soil additive, component of foundry sand, desiccant to remove moisture from air and gases, catalyst and various medicinal and pharmacological applications. This review article consists the various synthetic methods for preparation of catalysts based on MMT for organic syntheses and assessing their catalytic activities.

TL;DR: In this article , a montmorillonite (MMT) with high mechanical stability and negatively charged property is introduced on the surface of a porous poly(ether sulfone) substrate, which enables an efficient and highly stable alkaline zinc-iron flow battery.
Abstract: Alkaline zinc–iron flow batteries (AZIFBs) demonstrate great potential in the field of stationary energy storage. However, the reliability of alkaline zinc–iron flow batteries is limited by dendritic zinc and zinc accumulation, which has been treated as one of the most critical issues for the practical application of alkaline zinc–iron flow batteries. Herein, montmorillonite (MMT) with high mechanical stability and negatively charged property is introduced on the surface of a porous poly(ether sulfone) substrate, which enables an efficient and highly stable alkaline zinc–iron flow battery. The high mechanical strength of MMT can avoid damaging from metallic zinc, while its negatively charged property can effectively equilibrate the distribution of zincate ions at the interface between the membrane and the electrode. The synergistic effects of charge property and mechanical strength enabled by the montmorillonite flake layer can in turn effectively adjust the deposited zinc from “honeycomb-like” to “stick-like” morphology, thus affording the battery with a stable performance for 500 cycles at a current density of 140 mA cm–2, maintaining an energy efficiency of ∼80%. The results of this study are important for the regulation of zinc deposition morphology and the improvement of the operational reliability of zinc-based flow batteries.
