金属酸化物上の金属微粒子をモデル触媒とした研究の動向

抄録

Model catalysts for the metal nanoclusters supported on metal oxide have been studied from the view point of the unique catalytic reactivity of metal nanoclusters different from bulk materials. One of the most popular methods to prepare metal nanoclusters on oxide surfaces has been evaporation of metal. Techniques to control nano structures such as nanolithography and supporting nanoclusters synthesized in the gas or liquid phase have been also applied to surface chemistry especially during the past two decades. Several strategies to prepare model catalysts of metal nanoclusters supported on oxide, and two studies with Pt/TiO₂(110) model catalysts provoking discussion about the mechanisms of strong metal-support interaction (SMSI) and photocatalytic reactions are outlined.
