摘要
实践证明,在催化剂中引入助剂可显著提高催化剂性能,而有机物作为新兴的催化剂助剂因其成本低廉、绿色环保以及可特定调节催化剂性能等特点成为当前的研究热点。综述了5类常见的有机助剂(羧酸类、糖类、硅烷偶联剂类、有机胺类和醇类)在国内外的研究进展,重点探讨了不同助剂在催化反应中表现出的易与活性金属配位、预还原催化剂以及调变催化剂表面性质等方面的独特作用。分析对比了不同有机助剂的作用机理,以期为催化领域科技工作者设计和合成更加高效的催化剂提供一定的研究思路。有机助剂在催化领域展现出良好的发展前景,未来研究工作可着重于有机助剂作用机理方面的研究,从而获取系统的基础理论和实验数据,为有机助剂的进一步应用奠定基础。
Practice shows that the performance of catalyst can be significantly improved by introducing promoters.As a new catalyst promoter,organic compound has become a research hotspot because of its low cost,green and environmental protection and specific adjustment of catalyst performance.The research progress of five kinds of common organic promoters(carboxylic acids,sugars,silane coupling agents,organic amines and alcohols)at home and abroad is summarized.The unique functions of different promoters in catalytic reactions,such as easy coordination with active metals,pre-reduction catalysts and modifying the surface properties of catalysts,were discussed emphatically.To provide some research ideas for the scientific and technological workers in the field of catalysis to design and synthesize more efficient catalysts,the action mechanisms of different organic promoters were analyzed and compared.Organic promoters show good development prospects in the field of catalysis.In the future,the research work can focus on the mechanism of organic promoters,so as to obtain systematic basic theory and experimental data,and lay a foundation for the further application of organic promoters.
