Abstract
An advanced manufactured electrochemical reactor to convert air (N2+O2) to nitric acid (HNO3) and ammonia (NH3). The electrochemical reactor platform can be tailored via advanced manufacturing to improve activity, selectivity, energy efficiency and stability of the reactions.
Claims10
An apparatus for converting air to ammonia, comprising:
- an anode gas compartment, wherein said anode gas compartment is open to the air,
- an anode electrocatalyst operably configured to convert nitrogen from air to nitrate at the anode electrocatalyst by a nitrogen oxidation reaction,
- an electrolyte liquid compartment,
- a cathode compartment, and
- a cathode electrocatalyst operably configured to convert the nitrate to ammonia at the cathode electrocatalyst by a nitrate reduction reaction.
