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 and CTF-I is conducive to the activation of the inert N molecule in the electro-chemical process. As a result, 5% Mo/CTF-I exhibited an excellent faradaic efficiency of 27.3% and an NH yield rate of 7.23 μg h mg at -0.405 V RHE in 0.1 M KOH, surpassing most previous reports.
我们报道了一种智能离子交换策略，用于将氧化钼颗粒锚定在电荷调制的共轭三嗪框架（Mo/CTF-I）上以进行电化学固氮。MoO与CTF-I之间的强相互作用有利于在电化学过程中激活惰性N分子。结果，5%的Mo/CTF-I在0.1 M KOH中于-0.405 V（相对于可逆氢电极）时表现出27.3%的优异法拉第效率和7.23 μg h mg的NH产率，超过了大多数先前的报道。
