Germanium and phosphorus co-doped carbon nanotubes with high electrocatalytic activity for oxygen reduction reaction

Germanium and phosphorus co-doped carbon nanotubes (Ge–P-CNTs) were prepared by a simple and scalable approach.

Iron nanoparticles with a square pyramidal structure in mesoporous carbons as an effective catalyst toward oxygen reduction

FeAMC-1273, with more pyridinic-N and pyridinic-N–Fe for the creation of a square pyramidal planar geometry around iron, exhibits the best ORR activity.

Diamond@carbon-onion hybrid nanostructure as a highly promising electrocatalyst for the oxygen reduction reaction

The sp³-hybridized diamond structure was deliberately preserved at the core to retain stability, while modifying the sp²-hybridized surface carbon layers to enhance the ORR activity.
