Free nitrous acid-ultrasound pretreatment enhances cellulose conversion by complementary physical and chemical deconstruction.
Biorefining of cellulosic biomass has emerged as a promising strategy to address the global energy crisis and advance second-generation biofuel production. To overcome the inherent structural recalcitrance of cellulose, this study proposes a novel combined pretreatment strategy using free nitrous acid (FNA) and ultraso...
