Abstract Chlorine evolution reaction (CER) using dimensionally stable anode (DSA) materials are widely used in the chlor‐alkali industry. However, they still have problems such as high preparation cost, limited selectivity, titanium substrate being easy to passivate, [ 2 ] and electrode active material dissolve. Co 3 O 4 , a nonprecious metal material, has shown good catalytic potential promoting CER reaction, which broad application prospects electrocatalyst. In this paper, highly regular Rod‐like Fe, Bi co‐doped electrocatalyst was prepared. Compared with pure had larger electrochemical‐specific surface area, lower charge transfer resistance, better performance. 0.6 M NaCl solution, at current density of 20 mA/cm it achieves efficiency 91.8% degrades ammonia nitrogen an 82%.
