Two-step growth mechanism of supported Co3O4-based sea-urchin like hierarchical nanostructures [PDF]

, 2018
The formation mechanism of Co3O4-based sea-urchin like nanostructures from Co-O-B layers is unveiled. In this process, promoted by oxidizing annealing, B plays a major role, inducing first a chemical reduction of Co and the formation of a metallic ...
