The present invention relates to a new type of heterogeneous catalysts formed by a three-dimensional ceramic metal (cermet) structure, obtained by direct writing techniques (3D printing). One or more metals and one or more ceramic compounds in adequate proportions are used to make a paste (ink), whose rheological properties allow it to be extruded by 3D printing to form a pre-designed three-dimensional structure. After forming, the structure is processed thermally to obtain the consolidated cermet, with catalytically active metal phases in its body and on its surface.

La presente invención desarrolla un nuevo tipo de catalizadores heterogéneos metal- cerámicos (cermets). En ellos, la estructura “soporte” y las especies catalíticamente activas se integran en masa: el catalizador propuesto está formado por una estructura híbrida de uno o más metales y una o más fases cerámicas, conformadas conjuntamente en una estructura 3D prediseñada. El sistema de conformación puede variar de unos casos a otros, pero se proponen como más adecuadas las técnicas de escritura directa ( 3D Printing).
