Azo-bridged nitrogen-rich heterocyclic energetic compounds have high heat of formation and low mechanical sensitivity， making them widely applicable in the field of energetic materials. However， traditional preparation methods often involve oxidative coupling， suffering from high risks to safety and environment. In contrast， the electrochemical synthesis method is favored by researchers for its efficiency， controllability， and environmental friendliness. By adjusting the electrochemical reaction conditions， selective synthesis of azo-bridged nitrogen-rich heterocyclic energetic compounds with different structures can be achieved， opening up new possibilities for their synthesis. This study reviews the electrochemical synthesis methods， effects of electrolytes and electrodes， and possible reaction mechanisms of azo-bridged nitrogen-rich heterocyclic energetic compounds such as furazan， pyrazole， 1，2，4-triazole， and tetrazole. It is expected to provide a reference for the research and development of electrochemically synthesized azo-bridged nitrogen-containing heterocyclic energetic molecules.
