3d Flower-Like Nico2o4 Spinel Microspheres for Efficient Electrocatalytic Chlorine Precipitation

Previous research has shown that commercial DSA performs well in high concentration sodium chloride solutions in acidic solutions, but its chlorine evolution efficiency is not optimum in neutral settings. Second, commercial DSA is generally made up of noble metal oxides like RuO2, IrO2, Ta2O5, and so on. The rarity and expensive cost of precious metals limit their widespread use. As a result, a low-cost, high-efficiency 3D flower-like NiCo2O4 electrocatalyst was created using the hydrothermal approach. It exhibits good chlorine evolution activity and corrosion resistance in 0.6 M and 2 M NaCl solutions, with a chlorine evolution efficiency of up to 90%. It is critical that the electrocatalyst's chlorine evolution efficiency be greater than that of commercial DSA at any current density. The results of the 55 h stability test reveal that the electrocatalyst's voltage change is very minimal during the test, and it has outstanding stability and a long-term service life.
