a) Ru single atoms on Cu nanoparticles and the chemical reaction of dry reforming of methane. b) Reaction rate and stability of different catalysts with variable amounts of Ru concentration and c) their selectivity. Coke resistance of different catalysts d) pure Cu nanoparticles that are susceptible to form coke from dehydrogenated CH₄ (CH_x), e) Ru single atoms (Cu_19.9Ru_0.1 and Cu_19.8Ru_0.2) suppressed coking by isolating the CH_x intermediates, and f) high Ru concentration that produced coke.
