项目摘要

In the event of engineering greener methodologies for converting inedible-biomass into commodity chemicals over heterogeneous catalysts, various heterogeneous catalysts were developed. The preparation of metal-organic framework (MOF) based acid catalyst were successfully achieved through post-synthetic modification methodology. The prepared catalyst possessed acidic properties and catalytic activity for esterification and hydrolysis reaction comparable to the commercially known acid catalysts such as Amberlyst-15 and Nafions. In addition to the catalysis, the prepared acidic materials had potential for applications in fuel cells with high proton conductivity.The research also proposed the functionalization of MOFs to afford not only acid catalysts but also to immobilize metals like palladium (Pd) through amine functionalization. The successful incorporation of amine functionality was achieved through ligand design methodology and Pd was grafted on such material to afford a potent heterogeneous catalyst. Such catalyst demonstrated remarkable stability and catalytic performances for Mizoroki-Heck reaction. Surfactant-treated and/or stabilized monometallic and bimetallic nanoparticle based catalysts were also developed for various selective transformations including hydrogenation of olefins, oxidation of diols and cross-coupling reaction of aryl chloride.

在工程更环保的方法，将不可食用的生物质转化为商品化学品的多相催化剂的情况下，各种多相催化剂被开发。通过合成后改性的方法，成功制备了金属有机骨架酸催化剂。制备的催化剂在酯化和水解反应中具有酸性和催化活性，可与商业上已知的酸性催化剂如Amberlyst-15和Nafions相媲美。除了催化作用外，所制备的酸性材料在具有高质子导电性的燃料电池中具有应用潜力。该研究还提出了mof的功能化，不仅可以提供酸催化剂，还可以通过胺功能化固定钯（Pd）等金属。通过配体设计方法实现了胺功能的成功结合，并将Pd接枝到这种材料上以提供有效的多相催化剂。该催化剂在Mizoroki-Heck反应中表现出良好的稳定性和催化性能。表面活性剂处理和/或稳定的单金属和双金属纳米颗粒催化剂也被开发用于各种选择性转化，包括烯烃的加氢，二醇的氧化和芳酰氯的交叉偶联反应。
