Resumen
The steam reforming of ethanol was studied over supported Ni catalysts. The catalysts were prepared by the wet impregnation method, using chelating solutions (ethylendiaminetetraacetic acid, EDTA; nitrilotriacetic acid, NTA; and citric acid, CA). The solids were characterised by means of X-ray diffraction, BET specific surface area, temperature programmed reduction, X-ray photoelectron spectroscopy and thermogravimetry analysis. The catalyst prepared from EDTA solution was the most active and selective, with a low amount of carbon deposited after 7 h in reaction. This behaviour was associated with an improvement in the Ni-CeO2 interaction induced by the small NiO particle size obtained from the use of a chelating agent. This sample also showed a high Ce3+/Ce4+ ratio and the smallest particle size of metallic nickel.
