摘要：Efficient depolymerization of lignocellulosic biomass into platform chemicals is of great importance to bring the comprehensive bio-refinery concept into industrial reality. Herein, we reported an environmentally benign pretreatment process for full components utilization of moso bamboo in co-solvent of gamma-valerolactone (GVL) and aqueous solution of p-toluenesulfonic acid (TsOH aq). Notably, over 98 wt% of lignin and hemicelluloses could be simultaneously degraded into oligomeric phenols and pentose under the mild condition of 130 C for 60 min with GVL/TsOH aq volume ratio of 4/1, following with 91.5 wt% of cellulose retained which was then enzymatic hydrolyzed into 773.2 mg/g glucose. All of the obtained platform chemicals could be easily separated and purified, which significantly facilitate the excellent retrieve of the co- solvent. Moreover, the synergistic effect between GVL and TsOH on efficiency and specificity was proposed by control group experiment and verified by molecular dynamics simulation and quantum chemical calculation. This study provides a facile pretreatment and direct conversion strategy for biorefinery process of lignocellulosic biomass in novel GVL/TsOH aq co-solvent.
