Modifying graphene oxide with magnetic nanoparticles and Mg-Al LDHs and its application as an efficient catalyst in organic reactions
Abstract
Graphene oxide was synthesized and modified with Fe 3 O 4 magnetic nanoparticles, followed by integration of Mg-Al-OH LDHs into the GO matrix through solvothermal method. The formed magnetic Fe 3 O 4 @GO@Mg-Al-OH LDHs was then characterized using conventional analytical methods. SEM images showed agglomerated nanoparticles of the monohybrids with an average particle size between 40 and 80 nm. EDX and X-ray mapping confirmed the presence of all expected elements, including carbon, iron, aluminum, and magnesium. Furthermore, VSM analysis demonstrated that the magnetic properties of Fe 3 O 4 was meaningfully dropped in the final nanohybrid, although Fe 3 O 4 @GO@Mg-Al-OH LDHs still showed magnetic properties. The role of this nanohybrid as a catalyst was finally examined in the synthesis of isoxazolone and thiophene compounds.
