Aqueous phase synthesis and electronic spectroscopy of nanostructured layered double hydroxides

Abstract

Herein, we proposed a green synthetic route based on coordination chemistry to produce nanostructured layered double hydroxides (LDHs). The synthesized NiAl-, NiFe- and ZnAl-LDHs exhibited similar morphologies and crystal structures. A possible mechanism for LDH formation was proposed based on pH-potentiometric titrations. Extensive electronic spectroscopy analyses, interpreted through the lens of ligand field theory, provided key insights into the formation mechanism of NiFe-LDH.
