Oxidative mechanochemistry for direct, room-temperature, solvent-free conversion of palladium and gold metals into soluble salts and coordination complexes

Davin Tan, Tomislav Friscic, Jean-Louis Do
Noble metals are valued critical elements whose chemical activation or recycling is challenging, traditionally requiring high temperatures, strong acids or bases, or aggressive complexation agents. Using elementary palladium and gold, we demonstrate mechanochemistry for noble metal activation and recycling via mild, clean, solvent-free and room-temperature chemistry, leading to direct, efficient, one-pot conversion of the metals, including spent catalysts, to simple water-soluble salts, or to metal-organic catalysts.
