The bifunctional catalyst composed of Zn₂Al₃O₄ and Al-IDM-1 with 17-membered-ring pores and internal isolated silanols exhibits high propylene and butene selectivity accounting for 88 % in C_2–4⁼. The weak acidity prohibited the second reaction of olefins and isolated internal SiOH groups and promoted the desorption of C_3–4⁼ molecules.

利用分离的内部硅烷醇富集的 Al-IDM-1 铝硅酸盐纳米片促进合成气转化为烯烃

由Zn ₂ Al ₃ O ₄和Al-IDM-1组成的具有17元环孔和内部孤立硅烷醇的双功能催化剂在C _2–4 ⁼中表现出较高的丙烯和丁烯选择性，占88%。弱酸性阻止了烯烃的二次反应并孤立了内部的SiOH基团并促进了C _3–4 ⁼分子的解吸。
