Ion-pair complex precursor route for fabrication of high temperature shift Fe-Cr nanocatalyst

摘要

In the present research a high temperature shift Fe-Cr nanocatalyst was fabricated via thermolysis of an ion-pair complex precursor, [Fe(H_2O)_6][Cr(C_2O_4)_3]·4H_2O. This catalyst has higher specific surface area and smaller crystallite size compared to a reference catalyst prepared by precipitation-impregnation conventional method. The water gas shift activity of the prepared catalyst was comparable and even higher than that of a commercial catalyst in temperatures more than 400 ℃ and also, it showed better activity compared to that of the reference sample in all studied temperature range (350-500 ℃).
