| Περίληψη: | Recovering precious metals from spent automotive catalysts and realizing their high-value reuse is critical to ease resource shortages and advance sustainable industrial development. Conventional pyrometallurgical recovery consumes massive energy and generates secondary pollution; most existing techniques only extract Pd without exploring its subsequent high-value application. In this study, we developed an effective and green vacuum vaporization-deposition approach for the in-situ recovery and high-value utilization of palladium (Pd) from spent automotive catalysts. Under 1573 K and < 0.01 Pa, Pd was successfully transferred from spent automotive catalysts onto activated carbon (AC), enabling the preparation of a high-value Pd supported on activated carbon (Pd/AC) catalysts with a Pd loading of 61.42 mg/kg. During the process, no hazardous sulfur oxides such as SO (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
