One of the main challenges for catalysis has been direct methane conversion to useful products such as methanol and formaldehyde. Formaldehyde is currently produced by a three-step industrial process with syngas and methanol as intermediate products. MoO3 Fe2O3, and Fe2(MoO4)3 catalysts were used with four different Mo/Fe molar ratios (0.5, 1, 1.5, 2) in this work. The ferromolybdenum catalyst was prepared by coprecipitation. Pure oxides are more active; however they are not formaldehyde selective, but carbon oxide (CO, CO2) selective. The ferromolybdenum catalysts showed better HCHO selectivity at low conversions; the molybdenum oxide content did not show increased in catalytic activity. Increased reaction temperature did not increase formaldehyde selectivity.

Uno de los grandes retos para la catálisis ha sido la conversión directa de metano en productos químicos útiles a la industria tales como metanol y formaldehido. Actualmente el formaldehído es producido en un proceso que involucra tres pasos con gas de síntesis y metanol como productos intermedios. En este trabajo se emplearon catalizadores de MoO3, Fe2O3 y Fe2(MoO4)3 en cuatro proporciones Mo/Fe diferentes (0.5, 1, 1.5, 2). El catalizador de ferromolibdeno fue preparado por coprecipitación. Los óxidos puros presentan mayor actividad; sin embargo, no son selectivos a formaldehído, siendo los óxidos de carbono (CO, CO2) los principales productos. Los catalizadores de ferromolibdeno mejoran la selectividad a HCHO en detrimento del grado de conversión; el contenido de molibdeno no muestra incrementos en la actividad catalítica. El aumento en la temperatura de reacción no genera un aumento en la selectividad a formaldehído.
