One-pot transformation of furfural into γ-valerolactone catalyzed by a hierarchical Hf-Al-USY zeolite with balanced Lewis and Brønsted acid sites

A hierarchically structured bifunctional Hf-Al-USY zeolite with balanced Lewis and Brønsted acid sites has been developed as a robust catalyst for the one-pot conversion of biomass-derived furfural to γ-valerolactone.
