摘　　要：双功能催化剂的研究一直是纤维素降解制备高值化学品过程中催化剂研究的热点问题,但其在催化纤维素降解过程中还存在着催化机理不明确、目标产物选择性不高、水热稳定性不好等问题。本文简述了目前最受关注的含Ru、Ni、W、Pt等体系的双功能催化剂和不同载体影响下的双功能催化剂在纤维素制备C6多元醇、低碳多元醇（C2-C3）等化学品中的研究进展,初步总结了单金属、双金属体系和不同载体的双功能催化剂研究的前沿进展,分析表明不同活性金属之间配比以及活性金属与载体之间的相互作用均对催化效果产生重大影响;最后对其在纤维素制备多元醇中的应用前景进行了展望,指出继续研究活性金属之间及其与载体之间的相互作用将是今后研究的重点方向。The research on heterogeneous bifunctional catalysts （BFC） is the hot theme in cellulose processing to obtain green chemicals. But in this process,the BFC still had some fatal problems needed to be solved,such as the mechanism of the catalytic process,and its low selectivity for aimed products and hydrothermal stability. The research progress in most concerned BFC containing active metal components,such as Ru,Ni,W,and Pt,and the interacts between metal components and carriers for the application in cellulose to hexabasic alcohols and low carbon polyols （C2-C3）,were introduced, and the recent advances in mono-metallic,bi-metallic BFC and the BFC based on different carriers were simply summarized. The analysis results demonstrated the ratios of different metal components and the internal interacts between active metals and carriers had a great influence on catalytic results. The future study should be focused on the mechanism of interacts of catalytic constituents and carriers.
