摘要
分别从反应机理、活性位点、助剂和载体4个方面对合成气制低碳醇铑基催化剂体系进行了文献综述,同时对理想催化剂的研究方向做出了预测。通过对不同学者的研究成果的对比,发现对于铑基催化剂催化的反应机理和活性中心等方面的研究仍存在较多争议,更为深入仔细的研究工作仍然需要。应用前景方面,虽然铑基催化剂对该反应具有较高的低碳醇选择性(尤其是乙醇)和较好的稳定性,但较低的反应活性及铑金属自身昂贵的价格很大程度上限制了其应用,具有工业应用价值的高效铑基催化剂仍有待开发。
Literature reviews of Rh-based catalysts for higher alcohol synthesis has been made in this article. Mainly four topics of reaction mechanism,active sites,additives and carriers are discussed. We compared reports from different researchers,and found that controversies of reaction mechanism and active sites are still existed. Further researches are still needed. Though rhodium based catalysts exhibit high alcohol selectivity and good stability,its low reaction activities and high price still limit the large scale application,so efficient catalyst with high industrial applications values are still needed to study.
