Variations of iron(III) concentration were made during the synthesis of iron-copper-silicon oxide with sol-gel technique. The material was synthesized as a potential catalyst material for Fischer Tropsch reaction. A solution of sodium metasilicate was added dropwise onto solutions of iron(III) and copper(II) nitrate in diluted nitric acid. At pH 5 gels were obtained, followed with drying, calcination, and grinding to obtain fine powders. At concentration of iron(III) nitrate of 22.99% and 23.81% the process provided pale yellow colored powders, while those with 24.20%, 26.93%, and 27.58% of iron(III) nitrates gave brown powders. One of the brown powders showed crystalline phase in its diffractograms, while the yellow one was completely amorphous. © 2017 Author(s).
