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.
雙功能催化劑的研究一直是纖維素降解製備高值化學品過程中催化劑研究的熱點問題,但其在催化纖維素降解過程中還存在著催化機理不明確、目標產物選擇性不高、水熱穩定性不好等問題.本文簡述瞭目前最受關註的含Ru、Ni、W、Pt等體繫的雙功能催化劑和不同載體影響下的雙功能催化劑在纖維素製備C6多元醇、低碳多元醇(C2~C3)等化學品中的研究進展,初步總結瞭單金屬、雙金屬體繫和不同載體的雙功能催化劑研究的前沿進展,分析錶明不同活性金屬之間配比以及活性金屬與載體之間的相互作用均對催化效果產生重大影響;最後對其在纖維素製備多元醇中的應用前景進行瞭展望,指齣繼續研究活性金屬之間及其與載體之間的相互作用將是今後研究的重點方嚮.

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.
