We aimed to immobilize a complex of iron(III) amine bis(phenolate) on silica‐coated magnetic nanoparticles as a new magnetically recoverable catalyst (Fe3O4@SiO2‐APTES‐FeLGDC). Both the chemical nature and the structure of catalyst were confirmed by using field‐emission transmission electron microscopy, field‐emission scanning electron microscopy, FTIR spectroscopy, thermogravimetric analysis, vibrating sample magnetometry, X‐ray photoelectron spectroscopy, XRD, atomic absorption spectroscopy, and elemental analysis. This sustainable catalyst leads to the efficient oxidation of a wide range of alcohols and sulfides with excellent conversion and selectivity under a mild conditions to their corresponding oxidized products, acids (or ketones) and sulfoxides, respectively. Furthermore, the stability of the structure and morphology of our efficient recyclable system was investigated, and all of the data proved that the complex was anchored firmly to the magnetite nanoparticles.
An environmentally friendly and efficient catalyst containing three interesting parts, Mn, the amine bis(phenolate) ligand (H3LGDC) and the magnetic nanoparticles for benzylic C–H bond oxidation.
In this study, dilution analysis and anion exchange chromatography (AEC) were employed to provide insights into the photoluminescence (PL) of carbon nanodots (CNDs). A stepwise dilution process revealed that some of the fluorophores with higher energy emission were quenched in the high concentration solution and appeared in the dilute solutions. AEC fractionation led to seven sorts of CND frac-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
