Abstract: The greenhouse effect poses one of the significant challenges to humanity. Among the various greenhouse gases, CO2 accounts for 60% to 70% of the total contribution. Importantly, CO2 is thermodynamically stable and chemically inert, making its conversion a difficult task. Moreover, CO2 emissions will have a long-term impact on the environment. On the other hand, CH4 contributes approximately 20% to the overall greenhouse effect. Despite its relatively low concentration, a signal CH4 molecule has a global warming potential 25 times greater than that of a CO2 molecule. To mitigate the increasing concentrations of CO2 and CH4, many efforts have been developed. Among these, the reforming of CH4 and CO2 to syngas is a promising approach. This process not only helps in addressing climate change but also enables the production of value-added chemicals. In this respect, this reaction holds important theoretical significance and practical value.
