Manganese‐Modified Metal Nanoparticle Catalysts for Syngas to C2+‐Oxygenates

AbstractSyngas to oxygenates, in particular to alcohols containing two or more carbon atoms (i.e., C2+‐oxygenates), is one of the important research subjects in syngas conversion. The key to this process is the design and synthesis of efficient catalysts. Metal nanoparticle catalysts such as Rh‐based and Co‐based catalysts in the presence of Mn promoter are popular candidates for the syngas to C2+‐oxygenates, where the Mn effectively optimizes the dispersion of metal species and significantly influences the C─O dissociation and *CO insertion activity, thereby enhancing the yield of C2+‐oxygenates. In this review, the mechanism on the formation of C2+‐oxygenates from syngas was briefly discussed, typical examples were highlighted, design of efficient RhMn‐based and CoMn‐based catalysts for enhancing the C2+‐oxygenates yields was summarized, and the perspectives and challenges for catalyst design in this area were suggested.
