Synthetic Strategy

Reforming methane to produce syngas is a subject that generates considerable interest. The process requires catalysts that possess high-performance active sites to activate stable C–H bonds. Herein, we report a facile synthetic strategy to prepare Ni-based catalysts by complexation–impregnation (Ni-G/SiO2-C) and precipitation–impregnation (Ni-G/SiO2-P) methods using glycine as a complexing agent. The particle size of Ni in both types of catalysts is decreased by adding glycine in the preparation process. Nevertheless, the preparation methods and amount of glycine play a significant role in the particle size and distribution of Ni over the Ni-based catalysts. The smaller particle size and narrower distribution of Ni were obtained in the Ni-G/SiO2-P catalyst. The catalysts were comparatively tested for carbon-dioxide reforming of methane (CDR). Ni-G/SiO2-P showed better CDR performance than Ni-G/SiO2-C and Ni/SiO2 and increased stability because of the smaller particle size and narrower distribution of Ni. Moreover, a high-performance Ni-based catalyst was prepared by optimizing the amount of glycine added. An unobservable deactivation was obtained over Ni-G-2/SiO2-P and Ni-G-3/SiO2-P for CDR during TOS = 20 h. Thus, a new promising method is described for the preparation of Ni-based catalysts for CDR.

Carbon dioxide reforming of methane (CDR) can convert two greenhouse gases, methane can carbon dioxide, into useful syngas. Nickel-based catalysts have been extensively investigated due to their high activity and low cost. However, coke formation over Ni catalyst is serious and leads to rapid deactivation of the catalyst. Coke resistant Ni catalyst for CDR reaction is desired. In this paper, recent progresses in the design and preparation of coke resistant Ni catalysts supported on solid solutions, zeolite, perovskites and perovskite type oxides, hexaaluminates or substituted hexaaluminates, pyrochlore, montmorillonites, and hydrotalcites for CDR were summarized. The progresses in the use of promoters, in the effect of supporting materials and in the preparation methods have been discussed. The future development of coke resistant Ni catalysts for these processes is briefly addressed.
