Zirconia-based materials for catalytic conversions

Luxfer MEL Technologies supplies both doped and undoped zirconium compounds (hydroxides and oxides) for use in a wide range of catalytic applications. Materials are solid powders, with tunable properties resulting from our proprietary manufacturing processes. These are carried out at multi-ton scale. LMT also supplies zirconium solutions that are frequently used as binders (or indeed a Zr-source) in catalyst forming.

Easy separation from reaction media

Catalysts can be easily separated from the reaction media.

High activity / low temperature operation

Good interaction with supported metals, and properties can be modified by dopants.


They have developed (tunable) porosity and defined crystalline structure.


Particularly under hydrothermal (aqueous) conditions, ideal for ‘green’ processes.


Catalysts can be used several times during reaction cycle.

Environmentally friendly

Zirconia-based materials do not release any halogen containing or other compounds which might corrode equipment, impact eco-system.

*Other dopants can potentially be worked with, e.g. transition metal oxides, other rare-earth oxides, SnO2, Nb2O5, PO4.

Multiple dopants/combinations are also manufactured on a regular basis.

*Active sites may refer to acidity for example.

Typically has involved isomerisation of alkanes in gasoline upgrading (super-acid).

However, zirconia-based supports have attracted a lot of interest for “green” processes, for example cellulose conversion14. Other examples are shown on the next page.
