Methanol is a major fuel and chemical feedstock currently produced from syngas, a CO/CO /H mixture. Herein we identify formate binding strength as a key parameter limiting the activity and stability of known catalysts for methanol synthesis in the presence of CO . We present a molybdenum phosphide catalyst for CO and CO reduction to methanol, which through a weaker interaction with formate, can improve the activity and stability of methanol synthesis catalysts in a wide range of CO/CO /H feeds.
甲醇是目前由合成气（一种CO/CO₂/H₂混合物）生产的主要燃料和化工原料。在此，我们确定了甲酸根结合强度是限制已知催化剂在CO₂存在下合成甲醇活性和稳定性的关键参数。我们提出了一种磷化钼催化剂，用于将CO和CO₂还原为甲醇，该催化剂通过与甲酸根的较弱相互作用，可以在广泛的CO/CO₂/H₂进料范围内提高甲醇合成催化剂的活性和稳定性。
