Palladium oxide(II) CAS 1314-08-5

High-Purity Palladium(II) Oxide from Aure Chemical – Your Trusted Source

Palladium(II) oxide, PdO, CAS No. 1314-08-5, is a versatile heterogeneous palladium catalyst widely utilized in selective oxidation, hydrogenation, and hydrogenolysis processes across fine chemicals, pharmaceuticals, and advanced materials. Supplied by Aure Chemical as a black to dark brown powder with high palladium content (approximately 87–88% Pd), this stable oxide offers excellent activity, thermal stability, and resistance to common catalyst poisons. It functions directly as an oxidation catalyst or can be reduced in situ to active Pd(0) for hydrogenation applications, making it ideal for converting alcohols to aldehydes/ketones, dehydrogenation of hydrocarbons, reduction of nitro groups, and debenzylation reactions. Its robust performance under diverse conditions and ease of recovery make it a preferred choice in industrial-scale processes. Aure Chemical provides consistent particle size control, high surface area, and secure palladium sourcing to ensure batch reproducibility and optimal catalytic efficiency worldwide.
