Nickel-nitrogen-modified graphene (Ni-N-Gr) is fabricated and Ni-N coordination sites on Ni-N-Gr as active centers effectively reduce CO to CO. The faradaic efficiency for CO formation reaches 90% at -0.7 to -0.9 V versus RHE, and the turnover frequency for CO production comes up to ≈2700 h at -0.7 V versus RHE.
镍-氮修饰石墨烯(Ni-N-Gr)被制备出来,Ni-N-Gr 上的镍-氮配位作为活性中心有效将 CO 还原为 CO。在相对于 RHE 为-0.7 至-0.9 V 的电位下,CO 形成的法拉第效率达到 90%,在相对于 RHE 为-0.7 V 的电位下,CO 生成的周转频率高达 ≈2700 h。
