Palladium(II) nitrate
CAS 10102-05-3
Palladium nitrate is the halide-free palladium source for industrial catalyst manufacture — the impregnation precursor behind automotive three-way catalysts and chloride-sensitive supported Pd systems, supplied as solid or assayed solution.

Where Pd(NO₃)₂ is used
Emission-control catalyst manufacture
The standard Pd washcoat impregnation chemistry for three-way and diesel oxidation catalysts, where chloride-free dispersion preserves activity and substrate life.
Supported catalyst and materials synthesis
Used for chloride-free Pd/Al₂O₃ and Pd/zeolite preparation, and as a clean Pd²⁺ source in perovskite and mixed-oxide materials research.
Storage and shipping
Storage. Store sealed away from organics and reducing agents; oxidizing salt, hygroscopic.
Shipping. Oxidizer classification applies; shipped in UN-approved packaging with DG documentation.
Packaging. 25 g · 100 g · 500 g · Solution in DG-compliant carboys by contained Pd weight

Frequently asked questions
How is pricing structured?
Quotes reference the day's metal fixing on assayed contained metal plus a stated conversion charge, and can be locked at order confirmation for recurring volumes.
Solid or solution?
Catalyst plants running continuous impregnation take solution at a certified Pd g/L to skip dissolution and assay; solid suits smaller or intermittent users and ships at lower freight cost per gram of Pd.
Do you take back spent material?
Yes — spent catalyst, residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order, closing the loop on your metal inventory.
