高效的脱氧策略对于可再生原料的增值至关重要。脱氧脱水（DODH）使两个相邻的羟基直接转变为双键。负载型钼基催化剂首次在 DODH 中使用。与普通钼盐相比，MoOx /TiO2 显示出优异的催化活性。该催化剂在3-辛醇作为还原剂存在下有效地将1,4-脱水赤藓糖醇转化为2,5-二氢呋喃，表现出较高的重现性和稳定性。
Efficient deoxygenation strategies are crucial for the valorization of renewable feedstocks. Deoxydehydration (DODH) enables the direct transformation of two adjacent hydroxyl groups into a double bond. Supported molybdenum-based catalysts were utilized for the first time in DODH. MoOx /TiO2 showed superior catalytic activity compared to common molybdenum salts. The catalyst efficiently converted 1,4-anhydroerythritol into 2,5-dihydrofuran in the presence of 3-octanol as reducing agent, showing high reproducibility and stability.
