Abstract:

Currently, about 80% of all industrial chemical reactions are carried out with the help of catalysts or depend on catalytic processes. In this case, catalysts containing platinum group metals (hereinafter - PGM) occupy a special position due to their high catalytic activity and selectivity. A significant part of the net global demand for PGM is
for the production of catalysts, accounting for approximately 45% for platinum, 30% for palladium, 92% for rhodium, 35% for ruthenium, and 15% for iridium. The most important condition for the economical use of catalysts containing precious metals is their efficient recycling, which will be discussed further.
