Functional use of biomass based on its structural properties is an efficient approach for the valuable utilization of biomass resources. In this work, carboxymethyl cellulose zirconium-based catalyst (Zr-CMC) was constructed by the coordination between the carboxylic groups in sodium carboxymethyl cellulose (CMC-Na) with transition metal Zr. The prepared catalyst was applied into the synthesis of furfuryl alcohol (FAL) by catalytic transfer hydrogenation of biomass-derived furfural (FF) using isopropanol as hydrogen donor. Both the preparation conditions and the reaction conditions of Zr-CMC catalyst were investigated and optimized. The results showed that Zr-CMC was efficient for the reaction with the FF conversion, FAL yield and selectivity reaching to 92.5%, 91.5 %, and 99.0%, respectively, under the mild conditions (90°C). Meanwhile, the Zr-CMC catalyst could be reused at least for five times without obvious decrease in efficiency, indicating the catalyst had excellent stability. With the advantages of sustainable raw materials, high efficiency, and excellent stability, the prepared catalyst is potential for application in the field of biomass conversion.
基于生物质结构特性的功能性利用是生物质资源高值化利用的有效途径。在本工作中，通过羧甲基纤维素钠（CMC-Na）中的羧基与过渡金属Zr配位构建了羧甲基纤维素锆基催化剂（Zr-CMC）。将制备的催化剂应用于以异丙醇为氢供体，通过生物质衍生糠醛（FF）的催化转移氢化合成糠醇（FAL）反应中。对Zr-CMC催化剂的制备条件和反应条件进行了研究和优化。结果表明，Zr-CMC对该反应具有高效性，在温和条件（90℃）下，FF转化率、FAL产率和选择性分别达到92.5%、91.5%和99.0%。同时，Zr-CMC催化剂可至少重复使用5次，效率无明显下降，表明该催化剂具有优异的稳定性。所制备的催化剂具有原料可持续、效率高和稳定性优异等优点，在生物质转化领域具有潜在的应用价值。
