| Research Abstract |
Effects of interface between noble metal-support catalysts were investigated by quantum chemical simulation. Time course of aging phenomena of catalysts was estimated by particle-based simulation under the finite temperature. Additionally, tortuosity factor inside of the catalyst layer, which can not be experimentally obtained was successfully estimated. By this estimation method, diffusion coefficient was quantitatively evaluated, and its availability for for the different porous catalyst structure was demonstrated.
