Fabrication of Heterogeneous Exposed Core/Shell Catalyst Array Using the Space Specificity of an Embodied Micelle and Their Application to a High Performance Photocatalyst

摘要

Heterogeneous catalysts that exhibit synergistic catalytic effects in a lot of applications have attracted the great attention of many researchers.1-4 However, there is no reported method that allows deposition of each catalytic component at the specific position of a heterogeneous catalyst. In this respect, development of heterogeneous catalysts with the space specificity is still on a state-of-art technology. In the catalytic reactions, most of heterogeneous catalysts take a powder-type. However, catalysts on a powder-type have their limitation in that dispersion into aqueous media leads to the spontaneous agglomeration giving the rapid decrease of the catalytic activity.5-8 Also, thin film-type heterogeneous catalysts have other drawbacks resulting in irregular sizes and random distribution of the co-catalyst components.9-1
