Herein, an efficient and practical approach for dipolar modification of commercially available solid catalysts is reported. The solid catalysts HMS (hexagonal mesoporous silica)-DMSO decorated with organic dipolar layers are designed and synthesized by radiation technology under simple and accessible conditions. The dipolar catalysts can serve as platforms to introduce various active sites, benefiting
在此,报道了一种对市售固体催化剂进行偶极改性的有效且实用的方法。采用辐射技术在简单易得的条件下设计合成了有机偶极层修饰的固体催化剂HMS(六方介孔二氧化硅)-DMSO。偶极催化剂可以作为引入各种活性位点的平台,受益于偶极层的灵活性和多样性,这反过来又使它们能够在相对友好的系统中实现催化性能。具体而言,升级后的偶极催化剂 HMS-DMSO-SO 3 H 在将氧化的木质素模型化合物 α-羟基苯乙酮转化为 1,3-二氧戊环衍生物以及将异麦芽酮糖脱水为糖基氧基甲基糠醛 (GMF) 方面表现出良好的性能。
