摘要
Yan Qingyu et al.在其研究文章（e202502957）中报道，通过使用无定形CeMnOx电催化剂将*NHNH2→*NH2NH2步骤转变为*NHNH2→*NH+NH3步骤，实现了交替-远端杂化途径。在这个非常规的过程中，N2的活化是通过Mn位点上的π回给实现的，而Mn/Ce双活性位点可以调节中间构型，避免副产物的形成，从而促进NH3的合成。
An alternating–distal hybrid pathway is achieved by shifting the *NHNH2→*NH2NH2 step to an *NHNH2→*NH+NH3 step with an amorphous CeMnOx electrocatalyst, as reported by Qingyu Yan et al. in their Research Article (e202502957). In this unconventional process, N2 activation is realized through π back-donation on the Mn site, while the Mn/Ce dual active sites can regulate the intermediate configurations to avoid by-product formation, thus boosting NH3 synthesis.
