| 研究実績の概要 |
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.
