摘　　要：通过探究催化转移氢化(catalytic transfer hydrogenation,CTH)使高含氧量生物质加氢脱氧为高值平台分子的新策略,以实现生物质的资源化与利用和达成生产净零碳排放燃料的目标。文中以Zr/Hf金属氧化物非均相催化体系设计、构筑及性能调控为基本思路,以乙酰丙酸、糠醛、5-羟甲基糠醛及γ-戊内酯等重要生物质平台分子的可控定向转化为主线,重点评估了催化剂结构对应的酸碱活性位点在Meerwein-Ponndorf-Verley(MPV)反应中的关键作用,探讨并展望了Zr/Hf酸碱双功能催化剂在生物质平台分子转化为高值化学品领域的发展前景。本研究不仅对催化剂活性位点(Lewis/Br?nsted酸和碱)在相应生物质转化过程中的反应机理做出了归纳和总结,并且提出了兼顾经济效益和环境影响的新型固体酸催化剂的设计思路和策略。By exploring the new strategy for catalytic transfer hydrogenation(CTH) to hydrodeoxygenate high-oxygen-content biomass into value-added platform molecules in this research, the biomass resources utilization and the goal of producing net zero carbon emissions fuels were achieved. This review focused on the design, construction, and performance regulation of Zr/Hf heterogeneous catalytic systems. The controlled directional transformation of important biomass platform molecules such as levulinic acid, furfural, 5-hydroxymethylfurfural, and γ-valerolactone was described. Also the key role of acid-base active sites corresponding to the catalyst structure in Meerwein-Ponndorf-Verley(MPV) reaction was emphatically evaluated. Then the development prospect of Zr/Hf acid-base bifunctional catalyst in the conversion of biomass platform molecules into high-value chemicals was discussed. This review not only summarized the reaction mechanism of the active sites( Lewis/Br?nsted acid and base) in the corresponding biomass conversion process, but also proposed the design and strategies of novel solid acid catalysts that take into account economic benefits and environmental impacts.
