Xylitol is commonly known as one of the top platform intermediates for biomass conversion. Catalytic deoxygenation of xylitol provides an atomic and energetic efficient way to produce a variety of renewable chemicals including ethylene glycol, 1,2‐propanediol, lactic acid and 1,4‐anhydroxylitol. Despite a few initial attempts in converting xylitol into those products, improving catalyst selectivity towards C−O and C−C cleavage reactions remains a grand challenge in this area. To our best knowledge, there is lack of comprehensive review to summarize the most recent advances on catalyst design and mechanisms in deoxygenation of xylitol, offering important perspective into future development of xylitol transformation technologies. Therefore, in this mini‐review, we have critically discussed the conversion routes involved in xylitol deoxygenation over solid catalyst materials, the nanostructures of supported metal catalysts for C−H, C−C and C−O bond cleavage reactions, and mechanistic investigation for xylitol conversion. The outcome of this work provides new insights into rational design of effective deoxygenation catalyst materials for upgrading of xylitol and future process development in converting hemicellulosic biomass.

木糖醇催化脱氧为可再生化学品：催化剂设计和机理研究的进展

木糖醇通常被称为生物质转化的顶级平台中间体之一。木糖醇的催化脱氧为生产各种可再生化学品，包括乙二醇，1,2-丙二醇，乳酸和1,4-脱水羟醇提供了一种原子能高效的方法。尽管在将木糖醇转化为那些产物方面进行了一些初步尝试，但提高催化剂对C0和CC裂解反应的选择性仍然是该领域的巨大挑战。就我们所知，缺乏全面的综述来总结木糖醇脱氧催化剂设计和机理的最新进展，为木糖醇转化技术的未来发展提供重要的观点。因此，在此迷你评论中，我们已批判性地讨论了固体催化剂材料上木糖醇脱氧的转化途径，CH，CC和C-O键裂解反应的负载金属催化剂的纳米结构以及木糖醇转化的机理研究。这项工作的成果为有效设计用于木糖醇升级的有效脱氧催化剂材料的合理设计和未来转化半纤维素生物质的工艺开发提供了新见识。
