Iron‐based nanoparticles have many technological applications ranging from energy storage to biomedicine. Their use in energy‐storage devices depends on their efficient incorporation into functional electrodes, a purpose for which pulsed‐galvanostatic electrodeposition (PG‐ECD) is an ideal method. In this study, we used PG‐ECD to prepare Fe‐nanoparticle electrodes from formamide media, and we investigated the morphology of the electrodeposits and the electrochemical properties of the plating solutions as a function of the additives used. We found evidence of unusual behavior for the sodium dodecyl sulfate additive, which acted as a supporting electrolyte under our chosen conditions, and fairly typical behavior for acetylacetone and poly(ethylene glycol) dimethyl ether. All three additives showed that they could be used to control the morphology of the electrodeposits, albeit through mechanisms in some cases different than those typical in aqueous solutions.
