ELECTROCHEMICAL MODULE FOR AMMONIA SYNTHESIS USING CATALYTIC ELECTRODE OF METAL NITRIDE, FABRICATION METHOD THEREOF AND AMMONIA SYNTHESIS METHOD USING THE SAME

摘要

The present invention relates to an ammonia synthesis module, and more particularly, to a module for synthesizing ammonia by using an ion-conducting metal oxide in which metal nitride is coated with a catalyst and an electrode material, an ion-conducting polymer, a solid acid mixture, or a composite separation membrane of solid acid[m1] mixture at a temperature range from 20 to 800°C, and to a method of producing the same, and a method of synthesizing ammonia using the same. The present invention provides an ammonia synthesis module using a separation membrane, the ammonia synthesis module including: an ion-conducting metal oxide, an ion-conducting polymer, or a plate-like ion separation membrane for separation of a solid acid component; two metal nitride or metal nitride composite electrodes applied to central parts of both sides of the plate-like ion separation membrane in a symmetric or an asymmetric form to act as an electrode and a catalyst; a power supply electrically connected to the two electrodes to supply electric power; and a reactor bonded through one surface of the ion separation membrane and a sealant to seal one cross section thereof. In particular, an ammonia synthesis module uses metal nitride as an electrocatalyst, thus having an advantage of efficient ammonia synthesis.
