description [Image: see text] Dry reforming of methane is conducted in a catalyst packed-bed dielectric barrier discharge (DBD) reactor aiming to improve the reaction efficiency. The MgO- and CeO(2)-promoted Ni/γ-Al(2)O(3) catalyst is tested to carry out the reaction. An interesting observation is that Ni/MgO_Al(2)O(3) integration provides ∼35 and 13% conversion of CH(4) and CO(2), respectively. The highest syngas ratio of 0.94 is obtained with Ni/MgO_Al(2)O(3), whereas the ratio is only 0.57 with Ni/CeO(2)_Al(2)O(3) and 0.64 with bare DBD. In addition, Ni/CeO(2)_Al(2)O(3) offers the highest selectivity (68%) of CO due to the oxygen buffer property of CeO(2). Finally, the optimal acid/base property is highly desirable for the dry reforming reaction.
