Nano Ruthenium Dioxide Dihydrate Powder
ZnoNova Materials·SP-R00102
Hydrous ruthenium dioxide in nano powder form, assayed at 99.5% RuO₂·2H₂O by ICP. RuO₂ is one of the two benchmark oxygen-evolution catalysts, and the hydrous form is also the classical high-capacitance material in pseudocapacitor research. We supply it as a raw powder with a per-batch certificate of analysis.

CatalysisGeneral precious-metal oxide catalysis.
What we do not claim- We publish the assay and the method. We do not publish BET, particle-size distribution or electrochemical performance for this powder, because we have not been given measured values for them — and we will not substitute figures from a different product.
- Purity is stated as a product specification. The supporting analysis is available to buyers as commercial documentation with a sample; it is not offered as an advertising endorsement by the testing laboratory.
- If your evaluation needs BET or a particle-size report on this specific powder, tell us and we will arrange the testing rather than estimate.
Questions buyers ask
Is this anode-side or cathode-side material?
Anode. RuO₂ is an oxygen-evolution catalyst. Our nano-platinum powder is the cathode-side hydrogen-evolution material. They are not interchangeable, and we would rather say so than sell you the wrong one.
Why the dihydrate rather than anhydrous RuO₂?
The hydrous form is what the pseudocapacitor literature is built on, and it behaves differently from calcined anhydrous RuO₂. Tell us which your process needs.
Do you also supply supported catalysts?
Yes — Pd/RuO₂/C is available for evaluation.
What quantities?
Evaluation quantities through to regular supply. Ask for the current price ladder, since precious-metal pricing moves.
