Carboxymethyl cellulose assisted morphology controlled synthesis of MnO nanostructures for adsorptive removal of malachite green from water.

The physicochemical properties of manganese oxides and their different applications mainly depend upon their crystallite size, morphology, phase structure, and surface properties, which are again dependent on the preparation methods. So, a simple, cost-effective, and versatile synthesis method for such materials is highly desirable. Intending to accomplish this, herein we report the synthesis of MnO nanostructures by alkaline hydrolysis of the corresponding metal ions in an aqueous medium.

Ultrasonic irradiation-assisted MnFeO nanoparticles catalyzed solvent-free selective oxidation of benzyl alcohol to benzaldehyde at room temperature.

Magnetic nanoparticles (NPs) play a vital role in heterogeneous catalysis because of their easy separation, and effective recyclability. Herein, we report the synthesis of MnFeO NPs for use as catalysts in the selective oxidation of benzyl alcohol to benzaldehyde under mild conditions. The MnFeO NPs have been synthesized by precipitation method followed by hydrothermal ageing at 180 °C for 4.

Template-Less and Surfactant-Less Synthesis of CeO Nanostructures for Catalytic Application in -hydroxylation of Aryl Boronic Acids and the aza-Michael Reaction.

Due to its excellent physicochemical properties, CeO has found great importance as an electrochemical and in electronics, photocatalysis, sensing, and heterogeneous catalysis. Herein, we report the surfactant-less and template-less synthesis of CeO nanostructures by the hydrothermal method. The synthesized CeO nanostructures have been characterized in detail by electron microscopy, spectroscopy, diffractometry, and other analytical methods.

Rapid and enhanced adsorptive mitigation of groundwater fluoride by Mg(OH) nanoflakes.

Fluoride is one of the most abundant anions in groundwater, posing a significant threat to the safe drinking water supply worldwide. Fluoride contamination in drinking water at levels greater than 1.5 mg L causes a variety of serious health problems.

Facile synthesis of chitosan-modified ZnO/ZnFeO nanocomposites for effective remediation of groundwater fluoride.

This study explores the possibility of developing an eco-friendly adsorbent for effective remediation of groundwater fluoride, a well-known health hazard affecting more than 25 nations on the various continents. A facile and milder approach has been adopted to synthesize chitosan-modified ZnO/ZnFeO nanocomposites. The synthesized materials have been characterized by different spectroscopic, microscopic, and diffractometric techniques.
