| Summary: | Dry reforming of methane (DRM) offers a promising pathway towards carbon neutrality by converting the greenhouse gases methane (CH 4 ) and carbon dioxide (CO 2 ) into valuable syngas (CO + H 2 ). This sustainable process not only mitigates climate change but also contributes to a circular carbon economy by utilizing waste gases as valuable feedstocks. However, the successful industrial implementation of DRM hinges on the development of stable and efficient catalysts. This study investigated the influence of the ceria support source on the catalytic performance of Ni/CeO 2 catalysts. Three commercially available ceria supports from Germany, Canada, and the USA were employed, denoted as Ni-P, Ni-M, and Ni-C, respectively. These supports were impregnated with nickel and characterized using a suite of techniques, including XRD, FTIR, SEM, N 2 adsorption-desorption, and TGA. Catalytic activity and stability were evaluated within a temperature range of 550 to 750 °C. Our findings revealed that the catalytic performance is significantly influenced by the physicochemical properties of the catalyst. The Ni/CeO 2 (Ni-C) catalyst demonstrated superior activity and stability, exhibiting minimal carbon deposition as evidenced by TGA analysis and a low deactivation factor. This research provides valuable insights into the critical role of support materials in optimizing Ni/CeO 2 catalyst performance for DRM. The development of highly stable and active catalysts, such as the Ni/CeO 2 (Ni-C) catalyst, is crucial for the successful industrial implementation of DRM, contributing to a more sustainable and environmentally friendly energy future. |
