Summary: Phosphoric acid plus hydrogen peroxide (PHP) pretreatment effectively fractionated lignocellulosic biomass into cellulose-rich polysaccharides, water-soluble polysaccharides, and lignin fractions, allowing for their further conversion into biofuel and biomaterials. The PHP treatment disrupted the recalcitrant structure of lignocellulose, removing nearly 100% hemicellulose and 50.5-83.6% lignin. It also enhanced the accessibility of cellulose hydrolytic enzymes, achieving 100% cellulose-glucose conversion and producing 18.4 g of bioethanol from 100 g of poplar hardwood. Additionally, PHP facilitated the production of water-soluble polysaccharides with a high carbohydrate purity (98.3%) and introduced carboxylic groups and aliphatic chains in lignin, enhancing its amphiphilic properties and forming stable lignin nanoparticles. This tailored PHP process enables the full conversion of agriculture and forestry residues into sustainable bioproducts.
