A new preparation method of catalyst for ammonia synthesis Original Research Article

The preparation of a new catalyst for ammonia synthesis on the basis of a carbon support relies on a thoroughly mixing of polyacrylonitrile (PAN) with inorganic salts Fe(NO3)3 and KNO3 being previously dissolved in dimethylformamid (DMF). A catalyst was reduced at the flow of N2H2 mixture before activity measurements. The preparation conditions, leading to the manufacture of catalyst showing higher activity at atmospheric pressure than an industrial iron fused catalyst, were found. The optimal composition of precursor and the temperature carbonization were found.
