Promoted Two-Step Ammonia Synthesis with CoOOH/Co foam at Ampere-Level Current Density and Nearly 100% Faraday Efficiency from Air and Water.

Ammonia (NH) is regarded as an essential hydrogen storage material in the new energy field, and plasma-electrocatalytic synthesis of NH (PESA) is an alternative to the traditional Haber-Bosch process. Here, a bifunctional catalyst CoOOH/CF is proposed to enhance the PESA process. Benefiting from the efficient activation of O by CoOOH/CF, NO yield rate can reach the highest value of 171.
