概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
The purpose of this study is to develop supported bimetallic catalysts in which ionic liquids (ILs) are immobilized on mesoporous silica SBA-15 and to study their structural properties in hydrogenation reactions. To understand therelationship between structural properties and reactivity, it is important to identify their characteristic properties. For this purpose, STEM characterization was performed, and the formation of alloy particles was confirmed.
実験 / Experimental
STEM images and EDS elemental mappings of the prepared Pt-Co/IL@SBA-15 were taken using JEM-ARM200F Thermal
結果と考察 / Results and Discussion
The formation of small bimetallic Pt-Co particles on the Pt-Co/IL@SBA-15 sample was confirmed from the STEM-EDS mapping images. Small bimetallic particles with enriched Pt-Co surfaces were mostly observed inside the pores of SBA-15.
