Catalytic hydrolysis of cellulose over solid acid catalysts is one of efficient pathways for the conversion of biomass into fuels and chemicals. High catalytic activity and easy separation from reaction media are two important factors for evaluating the performance of the solid acid catalysts for the cellulose hydrolysis. In this study, we report a core–shell Fe3O4@C-SO3H nanoparticle with a magnetic...
A novel willow-based solid acid catalyst was successfully prepared through sulfonation of pencil refill. This solid acid catalyst bearing SO3H and COOH groups shows macroporous structure, which is more suitable for conversion of cellulose into glucose, resulting in 78.0 % conversion and 65.0 % glucose yield at 160 °C for 8 h reaction time. Its activity was comparable to other carbon sulfonated acid...
The determination of the chemical composition of lignocellulosic material is a resource-consuming analytical challenge that usually requires several chromatography-based techniques. Minor cell wall components and degradation products are, therefore, often ignored. 1H NMR spectroscopy applied to acid hydrolysates offers a quicker and more complete means to analyze lignocellulosic materials. Excellent...
A carbonaceous solid acid catalyst bearing weakly acidic carboxylic and phenolic functional groups was facilely prepared by the pyrolysis of cow dung followed by KOH activation. The prepared carbonaceous material showed low activity for the catalytic hydrolysis of raw cellulose in water (3.6% glucose yield). However, after the cellulose was pretreated by mixing with the carbonaceous catalyst in a...
