Comparative study of Cu, Ag and Ag-Cu catalysts over graphite in the ethanol dehydrogenation reaction: Catalytic activity, deactivation and regeneration

[Display omitted] •The ability of copper to promote ethanol dehydrogenation under non-oxidative conditions is much higher than that of silver.•Addition of a low quantity of silver into copper catalyst results advantageous to improve metallic dispersion.•Addition of silver into copper catalyst has a...
