Supported Palladium Catalysts

ZnoNova Materials

Alongside unsupported nano palladium and the Pd/MWCNT composite, two supported grades are available for evaluation: Pd/CeO₂/C and Pd/RuO₂/C. This page states plainly what we can say about them today and what we are still waiting on from the manufacturer, because an evaluation started on vague data wastes your time first.

What a support is doing

A support is not inert packaging. It disperses the active metal so more of it is exposed, it stabilises particles against sintering, and in the case of a reducible oxide such as ceria it participates — supplying and accepting oxygen at the metal-support interface. That is why Pd on ceria behaves differently from Pd on plain carbon at the same loading, and why the support has to be part of your specification rather than an afterthought.

What we can state today

Pd/CeO₂/C	Palladium on a ceria–carbon support. Evaluation samples available.
Pd/RuO₂/C	Palladium on a ruthenium-oxide–carbon support. Evaluation samples available.
Related unsupported grades	Nano RuO₂·2H₂O 99.5% · nano palladium powder · Pd/MWCNT (5/95)

Full technical datasheets for these two grades are not yet in our hands. Metal loading, support surface area and particle size are being prepared with the manufacturer. We are not going to fill that gap with plausible numbers.
We will not quote a turnover frequency or a conversion figure. Those belong to a reaction, a reactor and a feed, not to a powder.
If your evaluation depends on a specific loading, tell us the number you need and we will put the question to the plant rather than guess at what is available.

How to run a useful first evaluation

Name the reactionHydrogenation, oxidation, coupling, electrochemistry — the support choice follows from it.

State the phase and conditionsLiquid or gas, temperature, pressure, and whether the feed carries sulphur or halide.

Say what you compare againstA benchmark you already use makes the result interpretable instead of merely interesting.

Ask for the CoAPer-batch analysis is available on request and should be part of your record from the first sample.

Questions buyers ask

What is the palladium loading?

We do not have the confirmed figure for these two supported grades yet and we will not estimate it. Tell us the loading your evaluation needs and we will ask the manufacturer directly.

Why ceria rather than plain carbon?

Ceria is a reducible oxide that stores and releases oxygen at the metal-support interface, which changes behaviour in oxidation chemistry compared with an inert carbon support. Whether that helps depends entirely on your reaction.

Is Pd/RuO2/C for electrolysis?

Ruthenium oxide is an oxygen-evolution material, so the combination is of interest electrochemically, but we will not claim an electrode performance we have not been given data for. For OER as a raw material, our nano RuO2 powder is the established route.

Can we get samples now?

Yes. Evaluation samples of both are available while the full datasheets are being prepared.
