Abstract: We report a smart ion-exchange strategy to anchor molybdenum oxide particles on charge-modulated conjugated triazine frameworks (Mo/CTF-I) for electrochemically fixing nitrogen. The strong interaction between MoO<subscript>x</subscript> and CTF-I is conducive to the activation of the inert N<subscript>2</subscript> molecule in the electro-chemical process. As a result, 5% Mo/CTF-I exhibited an excellent faradaic efficiency of 27.3% and an NH<subscript>3</subscript> yield rate of 7.23 μg h<superscript>−1</superscript> mg<subscript>cat.</subscript><superscript>−1</superscript> at −0.405 V vs. RHE in 0.1 M KOH, surpassing most previous reports.
