<p>Vanadium is a strategically significant metal, indispensable to modern industries due to its unique physical and chemical properties. In this study, three dynamic optimisation challenges are addressed: controlling ionic valence states, regulating irregular product morphologies, and reducing carbon dioxide (CO₂) emissions. A simple and innovative method for producing metallic vanadium via electrolysis of a nitrogen-doped vanadium consumable anode (VC_<i>x</i>N_<i>y</i>O_<i>z</i>) is proposed and validated. The research compares the polarisation behaviour and reduction mechanisms of vanadium ions to metallic vanadium using two types of consumable anodes (VC_<i>x</i>N_<i>y</i>O_<i>z</i> and VC_<i>x</i>O_<i>y</i>). Nitrogen doping stabilises the V²⁺ ion through sp²-hybridised C–N coordination, promoting the formation of a stable [VN₆]^3– octahedral complex via V–N bond interactions. The study demonstrates that the VC_<i>x</i>N_<i>y</i>O_<i>z</i> anode effectively regulates the valence state of vanadium ions in molten salt systems, enabling a uniform dendritic morphology and achieving a 30% reduction in CO emissions compared to the VC_<i>x</i>O_<i>y</i> anode.</p> Graphical abstract <p></p>
