Description of the technology offer
The research group working on the “Structure and chemistry of nanomaterials” has developed a new catalyzer that does not contain noble metals in its formulation, has a low content in lanthanides and presents good oxygen storage properties. These catalyzers will be of great interest for the purification of the exhaust gases of combustion engines, and in the catalysis of any reaction in which the activation of hydrogen molecules is required.
New and innovative aspects
Since the 1990's, the mixed oxides of cerium and zirconium have replaced cerium oxide in the composition of the three-way catalyzers used in the automotive industry. The fundamental reason for this is the improved textural behaviour of the oxides of Ce/Zr, compared with the effectiveness of cerium oxide. These mixed oxides are also more effective in the exchange of oxygen with the medium. The Oxygen Storage Capacity (OSC) of the compound is therefore the key property for its ... Read more
