Title
A novel Ni–Mg–Al-LDHs/γ-Al2O3 Catalyst Prepared by in-situ synthesis method for CO2 reforming of CH4
Abstract

•Ni–Mg–Al-LDHs/γ-Al2O3 Prepared by in-situ synthesis method.•The catalyst precursor was calcined and reduced by atmospheric cold plasma.•The catalyst showed excellent performance in CO2 reforming of CH4.•The molecular-class dispersion of active component resists carbon deposition.

A novel Ni–Mg–Al catalyst derived from layered double hydroxides (LDHs) which was prepared on γ-Al2O3 by in-situ synthesis method. The catalyst was evaluated by CO2 reforming of CH4 and a better catalytic performance was obtained compared with a reference catalyst of Ni/MgO/γ-Al2O3 prepared by impregnation. The novel catalyst was also characterized by XRD, N2-adsorption-stripping, TEM, TG and AAS (atomic absorption spectrum). The results showed that the excellent performance of the catalyst benefited from its larger specific surface area and smaller active-crystal grain which is due to the molecular-order dispersion of active components over the LDHs precursor.
