In this paper, the as-prepared metal-organic frameworks material UiO-66 and other Zr-MOFs were directly used as catalytic transfer hydrogenation (CTH) catalysts to catalyze furfural (FF) to furfuryl alcohol (FAL) with 2-propanol (IPA) acted as both solvent and hydrogen donor. The results showed that the as-prepared UiO-66 had satisfactory catalytic activity and selectivity in yielding FAL (97 %) from the CTH of FF at 140 °C within 5 h. Moreover, the as-prepared UiO-66 exhibited relatively stable catalytic activity over five cycles and easy regeneration. Interestingly, UiO-66 was also applicable for the CTH of the other aldehydes such as 5-hydroxymethyfurfural, 5-methylfurfural, 4-methoxybenzaldehyde, and n-hexanal to the corresponding alcohols, affording high product yields up to 98 %. This work provides a green, simple and sustainable process for the catalytic production of FAL from biomass-based furfural, which has certain significance for the sustainable utilization of biomass.

本文将制得的金属有机骨架材料UiO-66和其他Zr-MOF直接用作催化转移氢化（CTH）催化剂，以2-丙醇（IPA）催化糠醛（FF）转化为糠醇（FAL） ）既充当溶剂又充当氢供体。结果表明，所制得的UiO-66具有令人满意的催化活性和选择性，可以在5小时内从FF的CTH在140°C的条件下生成FAL（97％）。而且，所制备的UiO-66在五个循环中表现出相对稳定的催化活性并且易于再生。有趣的是，UiO-66还适用于其他醛（如5-羟基甲基糠醛，5-甲基糠醛，4-甲氧基苯甲醛和正己醛）的CTH生成相应的醇，可提供高达98％的高产物收率。这项工作提供了绿色，
