Introduction	This study presents a highly selective (>99%) tandem catalytic system for converting ethanol (up to 37%) into n-butanol via the Guerbet process. The system employs a bifunctional iridium catalyst combined with bulky nickel or copper hydroxides. These sterically hindered nickel and copper hydroxides are essential for catalysing the aldol coupling reaction of acetaldehyde, specifically yielding the C4 coupling product, crotonaldehyde. The iridium-mediated dehydrogenation of ethanol to acetaldehyde has facilitated the advancement of an ethanol-to-butanol process operable at lower temperatures.
