Ni(II)–Mg(II)–Al(III) catalysts for hydrogen production from ethanol steam reforming: Influence of the Mg content

• Mg–Ni–Al hydrotalcites were prepared by homogeneous precipitation method with urea.
• Derived mixed oxides were studied as catalysts in ethanol steam reforming.
• A thermal evolution model for the solids is proposed from characterization results.
• Mg/Ni molar ratio = 0.33 gives the best results of activity and carbon deposition.
