CuFe bimetallic nanoparticle was prepared by co-reduction with NaBH4 as reductant in ethylene glycol solution, and was tested as model catalyst for higher alcohol synthesis (HAS). The structure evolution during the reaction process was investigated. At early stage the CuFe bimetallic nanoparticle showed high total alcohol selectivity. However, the alcohol selectivity decreased with time on stream. At the same time the average chain length increased for both alcohols and hydrocarbons. It was observed directly by TEM and STEM mapping-EDS that the Cu and Fe components in CuFe bimetallic nanoparticle separated during reaction and the phase separation led to the decrease in alcohol selectivity and distribution change of products.
