Slow and irreversible conversion to palladium oxide

Hydrogen uptake only above 1000°C

Dissolution into liquid metal hydrides only at high pressure

Electroplating to trap hydrogen ions

Permanent bonding that forms palladium oxide

Formation of a reversible palladium hydride

Silvery-white appearance and corrosion resistance

Extreme softness making it shapeable without alloys

Photocatalytic water splitting only

Hydrogenation and cross-coupling reactions

Free-radical polymerization of polyethylene
