Abstract
In dry reforming of methane (DRM), coke deposition on the Ni-based catalyst is the main cause of instability of the process. Perovskite LaNiO 3 is a well-known highly active catalyst precursor for DRM, but the La-Ni catalyst derived from it is susceptible to severe coke deposition and thus difficult for practical applications. To improve its stability and activity, Co and Mn are introduced to develop a tri-metallic LaNi 0.34 Co 0.33 Mn 0.33 O 3 catalyst precursor. The role of Mn is to improve the stability of the catalyst, whereas Co is an additional active component to increase the reaction rates. A strong metal and support interaction mediated by MnO is noted in the tri-metallic catalyst, which contributes to a synergistic effect of the tri-metals to sustain the high activity and stability under the harsh conditions of DRM.
