Electrochemical Recycling of Platinum Group Metals from Spent Catalytic Converters

Metals, 2020
Platinum group metals (PGMs: Pt, Pd, and Rh) are used extensively by the industry, while the natural resources are limited. The PGM concentration in spent catalytic converters is 100 times larger than in natural occurring ores.
