A sub-4 nm PtCu 3 intermetallic catalyst with an L1 2 -ordered structure toward efficient activity and durability for oxygen reduction
Pt-based intermetallic alloys have shown bright prospects for promoting the activity and durability of fuel cell cathode oxygen reduction. However, avoiding particle sintering in the preparation of highly ordered platinum-based intermetallic compounds remains a challenge. In this work, urea was intr...

| Zusammenfassung: | Pt-based intermetallic alloys have shown bright prospects for promoting the activity and durability of fuel cell cathode oxygen reduction. However, avoiding particle sintering in the preparation of highly ordered platinum-based intermetallic compounds remains a challenge. In this work, urea was introduced for high-temperature co-reduction to obtain highly ordered intermetallic nanocrystals of ultra-small size ( |
