RR and BOR in AEM electrolyzers, yielding valuable nitrogen-containing compounds at both the cathode and anode.RR process, the adsorption energies of reactants, products, and intermediates on the catalyst surface are regulated by vacancy engineering of the Nid-band center, promoting the reduction of nitrates to ammonia.
Techno-economic analysis demonstrates that paired electrolysis offers a 1.21 times lower cost and a 1.42 times higher profit compared to non-paired electrolysis, highlighting the feasibility and economic attractiveness of this approach. By applying the strategy of paired in AEM electrolyzers, the groundwork is laid for the sustainable synthesis and industrial development of various high-value chemicals.
