A biochar catalyst with functional Brønsted-Lewis acid sites for enhancing hydroxymethylfurfural production from glucoseOA
The sustainable production of 5-hydroxymethylfurfural(HMF)from glucose remains a major challenge in advancing bio-based chemical platforms.Despite extensive research,achieving high HMF yields in environmentally friendly systems is hindered by the complexity of glucose conversion pathways.This study presents a novel bifunctional catalyst(B-TsFe),derived from cassava rhizome(CR)biochar and functionalized with Brønsted and Lewis acid sites.The catalyst design leverages the carbon-rich nature of CR,integrating p-toluenesulfonic acid(TsOH)and ferric chloride(FeCl_(3))to establish synergistic acid functionalities.Comprehensive characterization confirmed the presence of both acid site types and mesoporous structures conducive to catalytic activity.The catalyst’s performance was evaluated in a water-isopropanol(iPrOH)biphasic system,achieving a maximum HMF yield of 34.5 wt.%under optimized conditions(200℃,75 min,3:2 iPrOH:H_(2)O ratio).Furthermore,the catalyst maintained high activity over five reuse cycles with minimal loss in performance.Compared to conventional biochar-based catalysts,B-TsFe exhibits superior acidity,enhanced glucose conversion efficiency,and a lower environmental impact due to its renewable origin and green solvent system.This work offers an eco-efficient strategy for HMF synthesis,addressing key limitations in catalyst development and process sustainability.
