Cu‐Co‐based catalysts provide promising systems for higher alcohol synthesis (HAS) due to a synergistic dual‐site mechanism. Bimetallic Cu‐Co (alloy) nanoparticles are assumed to be the active sites, but cobalt carbide (Co2C) forming under reaction conditions also seems to influence the formation of C2+OH. Na‐doped Co‐modified Cu/ZnO/Al2O3 is applied as benchmark catalyst within the Carbon2Chem® subproject L4 providing suitable performance in terms of CO conversion and C2+OH selectivity. However, further optimization is required in order to develop an economically viable HAS process.
