Encapsulation of Cu nanoparticles within TS-1 zeolite: synergistic Cu–N coordination and CuO (111)/Cu (111) facet engineering for enhanced 1, 4-butynediol synthesis
Encapsulation of Cu nanoparticles within TS-1 zeolite: synergistic Cu–N coordination and CuO (111)/Cu (111) facet engineering for enhanced 1, 4-butynediol synthesis
研究概述
以邻菲啰啉配体保护策略将Cu纳米颗粒封装进TS-1沸石,利用Cu—N配位提升乙炔吸附,并协同暴露CuO(111)/Cu(111)晶面促进甲醛活化。限域结构抑制铜浸出,4.94%低铜负载催化剂的1,4-丁炔二醇选择性88%,10次循环活性损失很小。
