生物质作为生产有价值的化学品和燃料的碳源引起了极大的关注。与相应的基于化石的方案相比，源自生物质的环状含氧化合物的选择性开环氢化为催化合成增值含氧化合物提供了有前途的方法。需要不同的催化位点来执行不同类型的基本反应步骤（例如，含氧基团的吸附和活化，氢分子的缔合），因此这些位点的协同作用在选择性加氢转化中起着关键作用，近年来引起了越来越多的关注。在此，我们对糠醛、5-羟甲基糠醛、γ-戊内酯、三乙酸内酯及其由各种均相和非均相催化剂催化的衍生物。特别关注活性位点（包括布朗斯台德酸、路易斯酸、碱和金属位点）对两种不同环状 C-O 键的选择性断裂和相关氢化转化的协同效应。还讨论了反应机理，为指导用于生物质增值的多功能催化剂的设计提供了见解。最后，还分析了生物质衍生环状化合物协同催化开环转化的当前挑战和未来机遇。路易斯酸、碱和金属位点，关于两个不同环状 C-O 键的选择性断裂和相关的氢化转化。还讨论了反应机理，为指导用于生物质增值的多功能催化剂的设计提供了见解。最后，还分析了生物质衍生环状化合物协同催化开环转化的当前挑战和未来机遇。路易斯酸、碱和金属位点，关于两个不同环状 C-O 键的选择性断裂和相关的氢化转化。还讨论了反应机理，为指导用于生物质增值的多功能催化剂的设计提供了见解。最后，还分析了生物质衍生环状化合物协同催化开环转化的当前挑战和未来机遇。

Synergistic Catalysis for Promoting Ring-Opening Hydrogenation of Biomass-Derived Cyclic Oxygenates

Biomass has attracted great attention as a carbon source for the production of valuable chemicals and fuels. Selective ring-opening hydrogenation of cyclic oxygenates derived from biomass offers promising approaches for catalytic synthesis of value-added oxygen-containing compounds compared to corresponding fossil-based protocols. Different catalytic sites are required to perform distinct types of elementary reaction steps (e.g., adsorption and activation of oxygen-containing groups, association of a hydrogen molecule), and thus the synergistic effect of these sites plays a critical role in the selective hydrogenation transformation, which has attracted increasing attention in recent years. Here, we present a review of the ring-opening hydrogenation of the representative platforms of furfural, 5-hydroxymethylfurfural, γ-valerolactone, triacetic acid lactone, and their derivatives catalyzed by various homogeneous and heterogeneous catalysts. The particular focus is placed on the synergistic effect of the active sites, including Brønsted acid, Lewis acid, base, and metallic sites, on the selective scission of two different cyclic C–O bonds and related hydrogenation transformation. The reaction mechanism is also discussed to provide insights for guiding the design of multifunctional catalysts for biomass valorization. Finally, the current challenges and future opportunities in the synergistic catalytic ring-opening transformation of biomass-derived cyclic compounds are also analyzed.
