- •
Cobalt nanoplatelets, nanoparticles and nanoflakes are formed by electrodeposition; the influence of concentration, potential and transferred charge on morphology is analyzed;
- •
Three-dimensional diffusion control cannot justify potentiostatic current transients;
- •
Aggregative growth can explain the deviation from three-dimensional diffusion control;
- •
Transition from nanoplatelets to nanoflakes is controlled by pulsed electrodeposition;
