Bimetallic Cobalt Nanoparticles (Co–M): Synthesis, Characterization, and Application in the Fischer–Tropsch Process

General synthesis schemes for size and composition controlled, bimetallic Co–M (M = Mn, Cu, Ru, Rh, Re) nanoparticles is reported. Characterization was carried out on the single particle level using scanning/transmission electron microscopy to confirm the bimetallic nature of the nanoparticles. In-s...

Description
Summary:General synthesis schemes for size and composition controlled, bimetallic Co–M (M = Mn, Cu, Ru, Rh, Re) nanoparticles is reported. Characterization was carried out on the single particle level using scanning/transmission electron microscopy to confirm the bimetallic nature of the nanoparticles. In-situ synchrotron spectroscopy followed the near surface composition of the nanoparticles during oxidation and reduction treatments, as well as reactant gas conditions. The effect of the second transition metal on the Co reduction and Co surface concentration was studied, with Re being the most effective promoter to reduce the Co. The Co–M nanoparticles were tested for their CO hydrogenation (Fischer–Tropsch process) ability at industrial conditions of 20 bar and 250 °C, to understand the effect of a promoter in intimate contact with Co.
