The conversion of biobased furfural (FF) into furfuryl alcohol (FA) has immense industrial significance; however, the catalyst preparation methods for the conversion of FF to FA are demanding. We demonstrated a facile method, direct calcination of manganese(II) acetate tetrahydrate, to prepare an oxygen-vacant Mn₃O₄ catalyst for the catalytic transfer hydrogenation (CTH) of FF to FA. The characterization results of oxygen-vacant Mn₃O₄ along with commercial and conventional Mn₃O₄ indicate that surface oxygen vacancies, strong acid–base properties, and a porous structure facilitate the high yield of FA (>99%) obtained from FF at 220 °C for 4 h in isopropanol. The oxygen vacancy-mediated Mn₃O₄ could be reused five times without noticeable activity loss. Moreover, we confirmed that Mn₃O₄ obtained from various manganese(II) salts by the direct calcination method also exhibited good performance for the CTH of FF to FA.

用于糠醛催化转移加氢的氧空位介导的Mn ₃ O _{4 的}简便制备

生物基糠醛（FF）转化为糠醇（FA）具有巨大的工业意义；然而，FF 转化为 FA 的催化剂制备方法要求很高。我们展示了一种简便的方法，即四水合乙酸锰 (II) 的直接煅烧，以制备用于 FF 到 FA 的催化转移氢化 (CTH)的氧空位 Mn ₃ O ₄催化剂。氧空位 Mn ₃ O ₄以及商业和常规 Mn ₃ O ₄的表征结果表明表面氧空位、强酸碱性质和多孔结构有助于从 FF 在 220°C 下在异丙醇中 4 小时获得高产率 (>99%)。氧空位介导的 Mn ₃ O ₄可以重复使用五次而没有明显的活性损失。此外，我们证实，通过直接煅烧法从各种锰 (II) 盐中获得的Mn ₃ O ₄也表现出良好的 FF 到 FA 的 CTH 性能。
