Abstract: Hydrogenation of dioctyl phthalate is the most important method for the synthesis of cyclohexane-1, 2-dioctyl diphthalate, which is an environmentally friendly plasticizer. A nickel-based nano-catalyst Ni-AlO was prepared from a nickel-aluminum hydrotalcite precursor.

Furthermore, Ni-AlO was more stable than Ni-Al2O3. TEM, TPR and XPS characterizations revealed that the hydrotalcite precursor benefited for not only the dispersion of Ni, but also its interaction with the support, and in turn improved the catalytic performance of Ni-AlO.
