dc.description.abstract	Converting greenhouse gases (CHGs) (carbon dioxide (CO2) and methane (CH4)) into valuable products is an essential way to eliminate the negative impacts of global warming. The catalytic dry reforming of methane (DRM) by CO2 offers a viable route for the efficient utilization of these two potent GHGs to produce syngas (CO and H2) as a valuable fuel and chemical feedstock. Nickel (Ni)-based catalysts have been widely used in DRM reactions because of their relatively high reactivity as transition metals and low production costs. However, these catalysts suffer from unideal reactivity at low operating temperatures, unideal thermal stability with Ni sintering and resulted in severe coke formation on the catalyst surface leading to rapid deactivation. Hence, the main objective of this study is to design and develop a stable and robust catalyst with improved DRM reactivity and low tendency for deactivation. In this doctoral study, the design of different catalysts with excellent activity and high stability for the DRM process will be studied. To achieve excellent catalytic activity and stability, different catalyst fabrication strategies with relatively facile synthesis approaches will be employed, such as the effect of active metal loadings, catalyst structures, distinguished support materials and the addition of promoters have been evaluated in this study. Meanwhile, several characterization techniques have been used to thoroughly understand the physicochemical and structural properties of the developed catalysts to develop a structure-property relationship. Moreover, the recent status of catalyst development is discussed and compared with that of the catalyst developed in our study. Process simulations based on the catalytic DRM process were also evaluated and analyzed in this study to further guide the development of the DRM process and help achieve its commercialization in the future.
