Photoelectrochemical driving and clean synthesis of energetic salts of 5,5′-azotetrazolate at room temperature

A photoelectrochemical route with a W, Mo co-doped BiVO 4 film photoanode was exploited to drive the coupling reaction of 5-amino-1 H -tetrazole at the room temperature for clean synthesis of sodium 5,5′-azotetrazolate.
