| Abstract | An integrated model of sustainable circular economy applied to the case of platinum group metals (PGMs) contained into the automotive catalytic converters is described. The cycle consists of four major steps: A. Collection and pre-processing of spent catalytic converters, B. PGM recovery as nitrate or other salts, C. Production of nano-catalytic washcoat powder, and D. Production of novel low-PGM catalysts. This scheme of circular economy can be sustainable when low-cost catalytic materials, like copper, are used to partially substitute the PGMs in the autocatalyst. A novel low-PGM Cu-based catalyst was successfully designed and tested, demonstrating the potential for practical applications. |
