The combination of methanation with plasma-catalysis has emerged as a promising avenue for the electrification of power-to-gas technologies, representing a significant development in the transition to sustainable energy systems. The present study investigates the impact of low 5 % mol Ru loading on CeO2, focusing in the role of the metal in comparison to Ni and the metal-support interactions examined using CeO2 with different structures (nanoneedles, nanopowder) and Ru dispersion within the support. The catalyst Ru/NN with nanoneedles of ceria achieved CO₂ conversion of 70 % and CH₄ selectivity of 99 % at 1CO₂/4H₂, WHSV of 30 L h−1 gcat-1, 12 kgCO2 kgcat-1 h−1 and plasma input power of 8.9 W. The enhanced plasma-catalytic activity of Ru/NN can be attributed to the increased effective H2 dissociation, beneficial physicochemical and electrical properties attributed to the choice of support and optimal metal-support interaction. The lower dielectric capacitance calculated for this catalyst is the result of reduced charge storage and a faster response to the applied electric field. This produces less intense microdischarges and a more stable and uniform plasma environment.This work was supported by the Departamento de Ciencia, Universidad y Sociedad del Conocimiento of the Gobierno de Aragón [Project no.
