Phase Quantification of Carbon Support by X-Ray Photoelectron Spectroscopy (XPS) in Plasma-Synthesized Fischer-Tropsch Nanocatalysts
X-ray photoelectron spectroscopy was used to quantify the different types of carbon in Co/C, Fe/C, 30%Co-70%Fe/C and 80%Co-20%Fe/C nanocatalysts synthesized through plasma-spray technology and tested for Fischer-Tropsch synthesis. The results showed that metal nanoparticle size influences graphitization of the C support, on which the catalyst's surface area largely depends. [GRAPHICS] .
