Resumo: ABSTRACT The NiCo2O4 catalyst with spinel structure was prepared by a modified polymeric-precursor method using gelatin as an organic-directing agent. The obtained powder was characterized by XRD, TPR and tested on the partial oxidation of methane. The Rietveld analysis performed on the XRD pattern confirmed the crystallization of two phases, the spinel NiCo2O4, and a solid solution NixCo1-xO. TPR profile revealed that both phases are entirely reduced up to 610 °C. The catalyst showed CH4 conversion of 75 % with H2/CO ratio around 2 and no signal of deactivation by coke formation, such as confirmed by XRD and TG analysis carried out after the catalytic test.
