eng	Carbon-Based Supports for Nickel Catalysts: Structural and Textural Effects on CO2 Hydrogenation to Methane	Carbon-based materials, including zeolite-templated carbon (ZTC) and nitrogen-doped zeolite-templated carbon (N-ZTC), activated carbon, and graphene, offer high porosity and tunable surface chemistry, making them promising supports for Ni-based catalysts in CO2 methanation. In this study, Ni catalysts with 5 % and 20 % metal loadings were prepared by impregnation and subsequent reduction, and thoroughly characterized using XRD, N2 sorption, TEM, TG-DSC-IR, and XPS. The influence of support type, nickel loading, and Ni cluster size on structural and textural properties was investigated. Variations in surface area, metal dispersion, and support–metal interactions were correlated with expected catalytic behavior. Preliminary observations indicate that both the nature of the carbon support and Ni concentration strongly shape catalyst properties. These findings enhance current understanding of carbon-supported Ni catalysts and their potential for efficient CO2 methanation.	Ni catalysts;Carbon supports;CO2 methanation;Heterogenous catalysis
