In the November issue of Chem, Xiong and coworkers report the method of fine-tuning Fe atom numbers in Fe clusters coordinated to N on C. Compared with mono- and tri-iron centers, the di-iron center exhibited higher electrocatalytic activity for oxygen reduction reaction because it promoted side-on adsorption of O₂.

二聚铁位点有效激活氧分子

在《化学》杂志的11月刊中，熊先生及其同事报道了微调C上与N配位的Fe团簇中Fe原子数的方法。与单铁和三铁中心相比，二铁中心对氧气的电催化活性更高。还原反应，因为它促进了O _2的侧面吸附。
