Liberation of Cellulose from the Lignin Cage: A Catalytic Pretreatment Method for the Production of Cellulosic Ethanol

Catalytic pretreatment of lignocellulosic materials with a copper(II) phenanthroline catalyst is an efficient and selective method for the isolation of cellulose. The method loosens the wood matrix and liberates cellulose with high yields. The use of a catalyst, water as solvent, and oxygen as oxida...

Zusammenfassung:	Catalytic pretreatment of lignocellulosic materials with a copper(II) phenanthroline catalyst is an efficient and selective method for the isolation of cellulose. The method loosens the wood matrix and liberates cellulose with high yields. The use of a catalyst, water as solvent, and oxygen as oxidant make this process a promising and sustainable method to obtain biofuels.
