SummaryA selective recovery process of recovery platinum from spent automotive catalytic converters using a strong basic ion exchange resin was developed. Recovered Pt was characterized by FESEM-EDS technique and used for the preparation of 2wt% Pt/Al 2 O 3 catalyst powder samples. Catalytic activity comparison between catalysts based on recovered platinum and commercial Pt/Al 2 O 3 catalysts showed that the 2wt% Pt(recovered)/Al 2 O 3 exhibited a slightly higher peak combustion temperature (Tp=561°C) compared with the commercial 2 wt% Pt/Al 2 O 3 (Tp=555°C). Shifting our attention towards the NO oxidation to NO 2 , both catalysts showed a similar performance, reaching the highest conversion (~61%) at 310°C with no production of nitrous oxi
