Designing a new magnetic g-C3N4 nanocatalyst based on Ag nanoparticles supported by β-cyclodextrin for effective reduction of nitroaromatic compounds
Abstract In this study, we present the synthesis of a silver nanocomposite by utilizing a β-cyclodextrin (βCD) polymer anchored onto the surface of magnetic g-C3N4 (referred to as g-C3N4-Fe3O4/βCD-Ag). The structure and composition of the g-C3N4-Fe3O4/βCD-Ag nanocomposite were thoroughly characteriz...

| Summary: | Abstract In this study, we present the synthesis of a silver nanocomposite by utilizing a β-cyclodextrin (βCD) polymer anchored onto the surface of magnetic g-C3N4 (referred to as g-C3N4-Fe3O4/βCD-Ag). The structure and composition of the g-C3N4-Fe3O4/βCD-Ag nanocomposite were thoroughly characterized using various techniques, including FT-IR, FE-SEM-EDS, TEM, TGA, XRD, ICP, and VSM. This catalytic system exhibited excellent selectivity in reducing nitro groups, even in the presence of other reactive functional groups, resulting in high yields ranging from 85 to 98%. Moreover, the organometallic nanocatalyst could be easily recovered from the solution using an external magnet and demonstrated consistent catalytic activity over six consecutive runs with a slight decrease. |
