An increasing trend of metal dissolution can be ascribed to the physical phenomenon of increased collisions between the particles of the heterogeneous system. 30 , 31 Dissolution efficiency reached the maximum of 91% Pt, 94% Pd, and 87% Rh at 150°C; thereafter, increasing temperature showed a decline in PGM dissolution (87% Pt, 81% Pd, and 84% Rh at 150°C).
