采用二次合成法制备了具有孤立Lewis和Brnsted酸中心的双功能SnAlBeta分子筛，并将其用于一锅法合成增值化学品γ-戊内酯。通过Lewis和Brnsted酸位的相互作用，SN-Al-Beta能够催化呋喃甲醛转移加氢和水解制GVL的级联反应。脱铝程度和掺锡方式对催化剂的酸性和选择性有很大影响。在正丁醇中，当温度为180℃时，当反应温度为180℃时，Si/Al=0.63，Si/Al=0.473的SnAl-Beta 7催化剂的GVL产率可达60%。
A bifunctional Sn-Al-Beta zeolite which possesses isolated Lewis and Brønsted acid sites was prepared by a post-synthesis procedure and applied to the one-pot conversion of furfural to γ-valerolactone (GVL), a value-added chemical. Sn-Al-Beta was capable of catalyzing a cascade of the transfer hydrogenation and hydrolysis of furfural to GVL by the interplay of Lewis and Brønsted acid sites. The degree of dealumination and the tin-incorporation method largely influence the acid properties of the catalyst and the catalyst selectivity. A high yield of GVL up to 60% was obtained with Sn-Al-Beta 7 (Si/Sn = 63 and Si/Al = 473) at 180 °C in 2-butanol.
