Fe-Mo interactions and their influence on Fischer-Tropsch synthesis performance

▶ In Fe-Mo bimetallic catalysts, Mo interacts with Fe species via Fe-O-Mo bridge bonds. ▶ Fe-Mo interaction improves the dispersion of Fe species. ▶ Fe-Mo interaction leads to an electron transfer from Fe to Mo. ▶ The dispersion effect on the Fischer-Tropsch synthesis activity and methane selectivity is opposite to the electronic transfer effect.
