Effect of the catechol structure on the functionalization and magnetic properties of barium hexaferrite nanoplatelets.

ABSTRACT: In this study, barium hexaferrite nanoplatelets (BHF NPLs) were functionalized with different catechols, pyrocatechol (CAT), dopamine (DA), and caffeic acid (CAFA). Possible adsorption mechanisms, structural effects, and their potential impact on the functionalization and decomposition of the NPLs were investigated. We synthesized the BHF NPLs hydrothermally and functionalized them with catechols in an aqueous suspension (pH = 3) using ultrasonication or heating at 80 °C. We characterized the morphologies and size distributions of the core and functionalized BHF NPLs using transmission electron microscopy (TEM). The functionalization of the BHF NPLs was followed by electrokinetic measurements and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Mass fractions of ligand
