Biomass, a globally available resource, is a promising alternative feedstock for fossil fuels, especially considering the current energy crisis and pollution. Biomass-derived diols, such as 2,5-bis(hydroxymethyl)furan, 2,5-bis(hydroxymethyl)-tetrahydrofuran, and 1,6-hexanediol, are a significant class of monomers in the polyester industry. Therefore, the catalytic conversion of biomass to valuable diols has received extensive research attention in the field of biomass conversion and is a crucial factor in determining the development of the polyester industry. 5-Hydroxymethylfurfural (HMF) is an important biomass-derived compound with a C6-furanic framework. The hydroconversion of HMF into diols has the advantages of being simple to operate, inexpensive, environmentally friendly, safe, and reliable. Therefore, in the field of diol synthesis, this method is regarded as a promising approach with significant industrialization potential. This review summarizes recent advances in diol formation, discusses the roles of catalysts in the hydroconversion process, highlights the reaction mechanisms associated with the specificities of each active center, and provides an outlook on the challenges and opportunities associated with the research on biomass-derived diol synthesis.
生物质作为一种全球可得的资源，是一种有前景的化石燃料替代原料，尤其考虑到当前的能源危机和污染问题。生物质衍生的二醇，如2,5-双（羟甲基）呋喃、2,5-双（羟甲基）-四氢呋喃和1,6-己二醇，是聚酯工业中一类重要的单体。因此，生物质催化转化为有价值的二醇在生物质转化领域受到了广泛的研究关注，并且是决定聚酯工业发展的关键因素。5-羟甲基糠醛（HMF）是一种具有C6-呋喃骨架的重要生物质衍生化合物。HMF加氢转化为二醇具有操作简单、成本低廉、环境友好、安全可靠等优点。因此，在二醇合成领域，该方法被认为是一种具有重大工业化潜力的有前景的方法。本文综述了二醇形成的最新进展，讨论了催化剂在加氢转化过程中的作用，突出了与每个活性中心特异性相关的反应机理，并对生物质衍生二醇合成研究的挑战和机遇进行了展望。
