Abstract
|
|
|
|
The ability of Fe3O4 Fenton-like reaction to produce glucose from lignocellulosic biomass was investigated. Fe3O4 magnetite nanoparticles were chemically synthesized from iron salts (a mixture of 1 M FeCl2 and 2M FeCl3) using an ammonia solution (30% NH4OH). The synthesized Fe3O4 nanoparticles were further characterized by X-ray photoelectron spectroscopy, energy dispersive X-ray spectroscopy, scanning electron microscopy, and transmission electron microscopy. Reed stems and rice straw biomasses pretreated with optimized Fenton-like reagents (Fe3O4 and H2O2) increased glucose production by 177 and 87%, respectively, compared to the control without the catalysts.
