摘要

本研究开发了水热合成的含锆材料（Zr@C-T），通过Meerwein-Ponndorf-Verley反应将生物质衍生糠醛（FAL）选择性加氢升级为糠醇（FOL）。通过系统的结构表征，揭示了制备的Zr@C-T的物理化学性质，并对FAL-to-FOL转化的催化活性进行了详细的研究。调节Zr的负载显著改变了酸性和碱性位点的分布，这与FOL的产量直接相关。在最佳反应条件下，Zr@C-T材料的FAL转化率为98.1%，FOL收率为93.1%。动力学研究证实，制备的低Zr负载Zr@C-T材料为FAL-to-FOL转换提供了14.8 kJ/mol的低活化能。此外，制备的Zr@C-T材料也适用于多种不饱和分子的h转移升级，性能优异。提出了制备Zr@C-T材料中FAL-to-FOL转化过程中氢转移过程的合理反应机理。

Hydrothermal synthesis of porous Zr-containing materials for transfer hydro-upgrading of biomass derived furfural

In the present research, zirconium-containing materials (Zr@C-T) originated from hydrothermal synthesis were developed for the selective hydro-upgrading of biomass derived furfural (FAL) into furfuryl alcohol (FOL) through Meerwein-Ponndorf-Verley reaction. Systematical structural characterizations were undertaken to reveal the physicochemical properties of as-fabricated Zr@C-T, and the catalytic activity towards FAL-to-FOL transformation was investigated in detail. Regulating the Zr loading significantly altered the distribution of acid and base sites, which was directly related to the FOL production. Under optimal reaction conditions, the FAL conversion of 98.1 % and FOL yield of 93.1 % were achieved over Zr@C-T materials. Kinetical investigations verified that the as-fabricated Zr@C-T materials with low Zr loadings supplied low activation energy of 14.8 kJ/mol for the FAL-to-FOL conversion. In addition, the as-fabricated Zr@C-T materials were also applicable to the H-transfer upgrading of a variety of unsaturated molecules with high performance. Plausible reaction mechanism of hydrogen transfer procedure for the FAL-to-FOL transformation over as-fabricated Zr@C-T materials was proposed.
