“…The FPMD simulation (5 ps at 800 K) revealed that the Fe 1 Cu 1 @C 2 N system has very good thermal stability (Figure S14, Supporting Information). Note that during the period of revision, the Cu 1 0 –Cu 1 x + pair anchored on Pd 10 Te 3 alloy nanowires have been developed for selective and efficient electrochemical reduction of CO 2, the Zn–Co atomic pairs on N‐doped carbon support was experimentally achieved and the high activity toward oxygen reduction reaction was demonstrated . Thus, we believe that the highly stable and efficient Fe 1 Cu 1 @C 2 N catalysts could be synthesized by using CuCl 2 and FeCl 2 as the metal precursors.…”

By means of density functional theory (DFT) computations, the CO/O2 adsorption and CO oxidation pathways on the biatom catalyst, namely the heteronuclear Fe1Cu1@C2N, in comparison with its homonuclear counterparts Fe2@C2N and Cu2@C2N are systemically investigated. The reactions of O2 dissociation and CO oxidization with preadsorbed CO or O2 are comparably studied. The computations find that the heteronuclear species Fe1Cu1@C2N possesses high stabilities and is feasible to be synthesized experimentally. More importantly, the heteronuclear Fe1Cu1@C2N catalyst has even better catalytic activity toward CO oxidation than its homonuclear counterparts, especially, without suffering the CO‐poisoning problem. Considering the myriad of unexplored heteronuclear dimers that can be potentially anchored at appropriate supports, this work opens a new avenue and provides a useful guideline for further developing bimetal‐based nanocatalysts.

Polynary single-atom structures can combine the advantages of homogeneous and heterogeneous catalysts while providing synergistic functions based on different molecules and their interfaces.However,the fabrication and identification of such an active-site prototype remain elusive.Here we report isolated diatomic Ni-Fesites anchored on nitrogenated carbon as an efficient electrocatalyst for CO 2 reduction. The catalyst exhibits high selectivity with CO Faradaic efficiency above 90 %overawide potential range from À0.5 to À0.9 V(98 %at À0.7 V), and robust durability,r etaining 99 %o fi ts initial selectivity after 30 hours of electrolysis.D ensity functional theory studies reveal that the neighboring Ni-Fec enters not only function in synergy to decrease the reaction barrier for the formation of COOH* and desorption of CO,but also undergo distinct structural evolution into aC O-adsorbed moiety upon CO 2 uptake.

“…As demonstrated by Wang's group, the 2G RuTe NTs can serve as a physical template to fabricate a series of multicomponent RuTe/M (M = Pt, Pd, PtPd, and PdAu) NTs, as shown in Figure (23)–(26) . As a versatile strategy, the one‐pot introduction of Cu and Pd precursors simultaneously to Te NWs would result in the 2G Cu (0.10%)‐doped Pd 10 Te 3 alloy NWs (Figure (27)), and the doping of Cu suppressed the competing HER but facilitated the selectivity and efficiency for the electrochemical reduction of CO 2 …”

The jagged Pt NWs and Cu‐doped Pd 10 Te 3 alloy NWs exhibit excellent catalytic activity toward the oxygen reduction reaction (ORR) and the electrochemical reduction of CO 2 , respectively. Very recently, the Xia group proposed a comprehensive review on the colloidal synthesis and application of 1D metal nanostructures, which extensively discussed their unique structure–property relationships.…”

1D nanomaterials with high aspect ratio, i.e., nanowires and nanotubes, have inspired considerable research interest thanks to the fact that exotic physical and chemical properties emerge as their diameters approach or fall into certain length scales, such as the wavelength of light, the mean free path of phonons, the exciton Bohr radius, the critical size of magnetic domains, and the exciton diffusion length. On the basis of their components, aspect ratio, and properties, there may be imperceptible connections among hundreds of nanowires prepared by different strategies. Inspired by the heredity system in life, a new concept termed the “nanowire genome” is introduced here to clarify the relationships between hundreds of nanowires reported previously. As such, this approach will not only improve the tools incorporating the prior nanowires but also help to precisely synthesize new nanowires and even assist in the prediction on the properties of nanowires. Although the road from start‐ups to maturity is long and fraught with challenges, the genetical syntheses of more than 200 kinds of nanostructures stemming from three mother nanowires (Te, Ag, and Cu) are summarized here to demonstrate the nanowire genome as a versatile toolbox. A summary and outlook on future challenges in this field are also presented.
