A bifunctional Sn-Al-Beta zeolite which possesses isolated Lewis and Brønsted acid sites was prepared bya post-synthesis procedure and applied to the one-pot conversion of furfural to g-valerolactone (GVL), avalue-added chemical. Sn-Al-Beta was capable of catalyzing a cascade of the transfer hydrogenation andhydrolysis of furfural to GVL by the interplay of Lewis and Brønsted acid sites. The degree ofdealumination and the tin-incorporation method largely influence the acid properties of the catalyst andthe 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 8C in 2-butanol.
