ABSTRACT
Layered Double Hydroxides (LDHs) are lamellar mixed hydroxides containing positively charged main layers and undergoing anion exchange chemistry. Researches revealed that LDHs have high specific surface area, inherent metal atom dispersion, and alkalinity, which make them possible to become a good candidate catalyst material (Romero et al. 2014, Rezende et al. 2015, Zhang et al. 2014, Montañez et al. 2014). Ni-Mg-Al catalyst derived from LDHs has been prepared and used in the autothermal reforming of CH4 by Katsuomi Takehira (2004), and a higher catalytic activity was obtained by comparing with the conventional catalyst prepared by the impregnation method. Alak Bhattacharyya et al. (1998) synthesized a hydrotalcite clay catalyst via CH4-CO2 reforming and gained prospective excellent performances. In our previous work, we prepared NiCo-Al catalyst with LDH precursor for CH4-CO2
1 INTRODUCTION
With the rapid development of society and economy, fossil energy has been widely used. And the resulting experimental issues have aroused widespread attention in recent years (Feely et al. 2011, Wang et al. 2015, Saidi et al. 2015). Moreover, the finite-energy resource is difficult to meet the increasing energy demands of the society in the long run. Thus, the sustainable global development of energy and environment is a critical and strategic challenge.
