Converting extensive sugars into value-added 2,5-furandicarboxylic acid (FDCA) has been considered to be a promising approach to developing sustainable substitutes for chemicals from fossil resources. The complicated conversion processes involved multiple cascade reactions and intermediates, which made the design of efficient multifunction catalysts challenging. Herein, we developed a catalyst by introducing phosphotungstic acid (PW) and Co sites into the UiO-66, which achieved a one-pot cascade conversion of fructose-to-FDCA with high conversion (>99 %) and yield (94.6 %) based on the controllable Lewis/Brønsted acid sites and redox sites. Controlled experiments and detailed characterizations show that the multifunctional PW/UiO(Zr, Co) catalysts successfully affords the direct synthesis of FDCA from fructose via dehydration and selective oxidation in the one-pot reaction. Additionally, the MOF catalysts could also efficiently convert various sugars into FDCA, which has broad application prospects. This study provides new strategies for designing multifunctional catalysts to achieve efficient production of FDCA from biomass in the one-pot reaction.
将大量糖类转化为增值的2,5-呋喃二甲酸（FDCA）被认为是开发可持续替代化石资源化学品的一种有前景的方法。复杂的转化过程涉及多个级联反应和中间体，这使得设计高效的多功能催化剂具有挑战性。在此，我们通过将磷钨酸（PW）和钴位点引入UiO-66中开发了一种催化剂，基于可控的路易斯/布朗斯特酸位点和氧化还原位点，该催化剂实现了果糖到FDCA的一锅级联转化，转化率高（>99%），产率为94.6%。对照实验和详细表征表明，多功能PW/UiO(Zr, Co)催化剂在一锅反应中通过脱水和选择性氧化成功地从果糖直接合成了FDCA。此外，该金属有机框架催化剂还能有效地将各种糖类转化为FDCA，具有广阔的应用前景。本研究为设计多功能催化剂以实现一锅反应中从生物质高效生产FDCA提供了新策略。
