摘要

生物基木糖到糠醛的转化通常伴随着在评估热条件下的缩合/降解。本研究提出了一种可见光增强酸性和局部光热效应相结合的策略，用于室温级联异构化-脱水木糖至糠醛的超高收率（96.3%），其中路易斯酸性 Al3+ 中心可促进木糖的电子转移以启动异构化，Al3+-多酚复合物的形成可释放布氏酸以进行脱水，而原位共加生物石墨烯则可提供令人满意的光热条件。

Visible light-activated polyphenol–Al3+ coordination for ambient and quantitative xylose-to-furfural conversion†

Bio-based xylose-to-furfural conversion is often accompanied by condensation/degradation at evaluated thermal conditions. This study presents a combined strategy of visible light-enhanced acidity and local photothermal effect for room-temperature cascade isomerization-dehydration of xylose to furfural in an ultrahigh yield (96.3%), in which Lewis acidic Al³⁺ centers facilitate electron transfer from xylose to initiate isomerization and the formation of Al³⁺-polyphenol complex is enabled to release Brønsted acid for dehydration while co-added bio-graphene in situ offers satisfactory photothermal conditions.
