Abstract: 
The effect of metal precursor composition on the synthesis of iron oxide nanoparticles in a spray flame reactor was studied. Three compounds, iron nitrate, iron acetylacetonate, and ferrocene, were tested at 0.1 M and 0.2 M concentrations. Variation of the iron precursor showed significant effects in crystallinity, crystallite size, and iron oxides content; the ferrocene produced the highest hematite content, and the nitrate showed the greatest magnetite contribution. Besides, all the particle characteristics changed when the concentration was duplicated, which was found mainly determined by the positive influence of the iron catalytic effect on the flame energy. FTS catalysts were prepared by the FexOy@C samples carburization, obtaining different active phase (chi-Fe5C2) contents from 52% to 92% and depending on the iron precursor employed. Catalysts exhibited good performances for FTS with CO conversions up to 70% and selectivity to C5+ products from 59% to 71%.
