| Abstract [eng] |
The paper presents an analysis of literature data on production of hydrogen ant ammonia by electrochemical methods. Methods of zirconium nitride coatings deposition is presented in literature review. ZrN coatings were deposited by magnetron sputtering on AISI304 type stainless steel under different conditions. The structure, morphology and composition oh thin films were performed by instrumental analysis. The electrocatalytic activity of ZrN coatings were performed in 0,1 M KOH electrolyte using various electrochemical analysis techniques. The influence of the synthesis conditions on electrocatalytic activity of zirconium nitride thin films was determined. The highest activity is observed for nanostructured ZrN thin films with a ratio Zr:N = 1:0,73. It has been experimentally established that hydrogen evolution reaction dominates in 0,1 M KOH with N2 electrolyte. The principle technological scheme of alkaline water electrolysis is presented and the main technological parameters for production of 10 MW are calculated. Safety of plant is evaluated. |
