Steering Acid-Base Site Distribution and Hydrophobicity of Bioresourced Bifunctional Hybrid Materials for Direct Synthesis of γ-Valerolactone from Biomass-Based Furfural.

The direct production of value-added chemicals from biomass via multiple conversion processes with a sole renewable solid catalyst is promising for carbon-neutral development while challenging. Herein, a series of novel bioresourced organic-inorganic hybrid materials were synthesized from bio-based ascorbic acid (Vc), zirconium chloride (ZrCl) and p-toluenesulfonic acid (p-TSA) through a facile solvothermal process. The as-prepared Zr-Vc-3 catalyst with Vc, ZrCl, and p-TSA in the 1 : 1:0.
