With the increasing demands for energy and carbon resources, exploration of novel utilization approaches of fossil resources and promotion of the conversion of sustainable resources become critical issues facing human society. In this study, we used humic acids (HAs), which are important derivatives from the low-rank coal, and the transition metal zirconium (Zr) to construct novel Zr-containing catalysts (Zr-HAs) for Meerwein–Ponndorf–Verley (MPV) reactions of biomass-derived platforms. Both commercial HAs and HAs extracted directly from lignite without any purification were used as raw materials to prepare the catalysts. The results showed that Zr-HAs catalysts were highly efficient for the conversion of furfural, with a high furfuryl alcohol yield of up to 97%, and also effective for the conversion of other carbonyl compounds with different structures under mild conditions. This novel strategy to construct catalysts using HAs as raw materials may be beneficial for both value-added utilization of low-rank coal and the conversion of biomass resources.

直接使用腐殖酸混合物构建Meerwein–Ponndorf–Verley反应的高效含Zr催化剂

随着对能源和碳资源的需求不断增长,探索化石资源的新型利用方法和促进可持续资源的转化已成为人类社会面临的关键问题。在这项研究中,我们使用了腐殖酸(HAs)(它们是低阶煤的重要衍生物)和过渡金属锆(Zr)来构造用于Meerwein-Ponndorf-Verley( MPV)生物量衍生平台的反应。商用HA和未经任何纯化直接从褐煤中提取的HA均用作制备催化剂的原料。结果表明,Zr-HAs催化剂对糠醛的转化非常有效,糠醇的收率高达97%,在温和条件下也能有效转化具有不同结构的其他羰基化合物。这种以HAs为原料构造催化剂的新颖策略可能对低阶煤的增值利用和生物质资源的转化都有利。
