| Outline of Final Research Achievements |
Hydrolysis/polycondensation of trialkoxysilanes was carefully conducted to preserve Si-H ligands followed by the sol-gel transition accompanied by phase separation, which lead to the formation of hierarchically macro/meso-porous hydridosilica monoliths. By introducing noble metals solutions with optimized solvent composition into the hydridosilica monoliths, metal/alloy nanoparticles were formed in a controlled manner. The catalytic performance was evaluated using the monolithic flow-through reactors with embedded metal/alloy nanoparticles as catalysts. Dehydrogenation catalyzed by borane catalyst was also explored to modify silica supports with well-defined pore structure with polymeric reagents bearing Si-H groups. The metal/alloy nanoparticles were produced on the surface of silica support of which catalytic performance was examined in detail.
