| 中文摘要 | a quantitative electron tomography study of ruthenium particles on the interior and exterior surfaces of carbon nanotubes |
| 英文摘要 | the efficiency of filling carbon nanotubes (cnts) by ultrasound-assisted wet impregnation is quantified by electron tomography (et). for image analysis, a method that combines edge detection with single-value thresholding is proposed and validated. a high proportion (80 wt%) of the ruthenium was deposited inside the tube at an average particle size of 24 nm. particles located on the outer surface of the cnt had a size of 1-3 nm. the local ruthenium loading measured by et (3.2 wt%) closely matched the value from elemental analysis (3.5 wt%). in addition, a few 1 nm-sized ruthenium particles were detected inside the carbon wall, which contained pores/cracks. direct imaging and quantification is a powerful tool to understand and possibly model the unique properties of cnt-based catalysts. |
