Abstract: A set of synthesized Mg/Co/Al hydrotalciteswas synthesized and characterized by XRD, XPS, BET, SEM, TEM, and FT-IRphysical techniques. The partial substitutionofMg 2+ byCo 2+ inbrucite layers has not significantly affected the layered double hydroxide structure, but plays a crucial role in the oxidation of styrene in the presence of air. The prepared Mg/Co/Al hydrotalcite-like compounds express a good activity and stability in the oxidation of styrene in the free-solvent condition. Both styrene conversion and desired product selectivities are strongly dependent on the cobalt substitution content. The intra-hydrotalcite lattice Co 2+ ions are active sites for the epoxidation of styrene. © 2013 Elsevier B.V. All rights reserved
