Heterojunction nanowires having high activity and stability for the reduction of oxygen: Formation by self-assembly of iron phthalocyanine with single walled carbon nanotubes (FePc/SWNTs)

- FePc/SWNT heterojunction nanowires are prepared via a self-assembly approach.
- FePc/SWNT performs much better than Pt/C in the ORR in alkaline media.
- DFT and experimental results are combined to understand the ORR at FePc/SWNT.
- The O2-FePc interaction is facilitated with fast electron transfer to the surface.
