概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
In this study, we prepared transition metal single atom catalyst (SAC) supported on N-doped carbon with high selective for CO2R to CO. The prepared SACs manifest a well-defined graphene interconnected porous structure and highly distributed single metal sites.
実験 / Experimental
利用装置: 収差補正電子顕微鏡 (JEM-ARM 200F Cold) HR-TEM image: confirming structure of carbon matrix and formation of aggregated particles, in some cases we anticipated the formation of nickel nanoparticles.Aberration-corrected HAADF-STEM image: checking the degree of dispersion of atomically isolated metal atoms. STEM-EDS: along with the HAADF-STEM visualizing the distribution of each element, carbon, nitrogen, and transition metal.
結果と考察 / Results and Discussion
- From the HR-TEM
image, we could verify the amorphous carbon structure, and excessive
metal loading in preparing precursor induced the formation of metal
nanoparticles.
From
the HAADF-STEM image with EDS, the uniformly dispersed metal atom
could be confirmed.
EDS
result shows the average distance between hetero transition metal
atoms was 2.4 ~ 2.5 Å,
that is homogeneously dispersed on the carbon matrix.
