合成了含钙的FSM-16（Ca-FSM-16）固体碱催化剂，用于Knoevenagel缩合反应。扩展的X射线吸收精细结构（EXAFS）的结果表明，钙物种被引入到FSM-16的孔壁作为一个扭曲的四面体配位的硅酸钙样相。与传统的氨丙基功能化介孔氧化硅相比，Ca-FSM-16作为固体碱催化剂对Knoevenagel缩合反应具有更高的催化活性。
AbstractWe synthesized Ca-containing FSM-16 (Ca-FSM-16) for use as a solid base catalyst for the Knoevenagel condensation reaction. Extended X-ray absorption fine structure (EXAFS) results indicated that Ca species were introduced as a calcium silicate-like phase with distorted tetrahedral coordination into the pore walls of FSM-16. Compared with conventional aminopropyl-functionalized mesoporous silica, Ca-FSM-16 showed higher activity as a solid-base catalyst for the Knoevenagel condensation reaction.Graphical AbstractCa-containing mesoporous silica (Ca-FSM-16) was synthesized for use as a solid base catalyst for the Knoevenagel condensation reaction.
