Anisotropic N-Graphene-diffused Co₃O₄ nanocrystals with dense upper-zone top-on-plane exposure facets as effective ORR electrocatalysts.

ABSTRACT: We provide strong evidence of the effectiveness of homogenously self-propelled particle-in-particle diffusion, interaction and growth protocol. This technique was used for one-pot synthesis of novel nitrogen-graphene oxide (N-GO)/Co₃O₄ nanocrystals with cuboid rectangular prism-shaped nanorods (NRs) along {110}-plane and truncated polyhedrons with densely-exposed, multi-facet sites along {311} and {111} planes. These hierarchal nanocrystals create electrode catalyst patterns with vast-range accessibility to active Co²⁺ sites, a vascular system for the transport and retention of captured O₂ molecule interiorly, and low adsorption energy and dense electron configuration surfaces during the oxygen reduction reaction (ORR). The superior electrocataly
