Mg‐Ni‐Al‐CO 3 hydrotalcite‐like material was synthesized by coprecipitation method at a certain pH. The synthesized solids have been characterized by physical techniques, namely XRD, IR, TEM, and EDS. All synthesized samples showed a well‐defined hydrotalcite structure with the presence of nickel(II) ions in Mg‐Al hydroxide lattice. The Mg‐Ni‐Al‐CO 3 catalyst has been tested for the oxidation of styrene with aqueous hydrogen peroxide solution and showed a good catalytic activity in the formation of benzaldehyde. Styrene conversion is in the range of 20‐85 % with the high selectivity to benzaldehyde at 50‐80°C, 4 hours.
