“…Under alkaline conditions, the cathode oxygen reduction reaction (ORR) are kinetically accelerated on a richer variety of catalysts that can be composed by nonprecious elements, and endowed with improved stabilities compared to the acid scenarios. [7][8][9][10] However, the anode hydrogen oxidation reaction (HOR) is severely repressed in alkaline conditions even by the state-ofthe-art Pt and/or its derived electrocatalysts, presenting ≈2 orders of magnitude lower activities than that in acidic media. [11] More fatally, these catalysts tend to be poisoned by trace CO in H 2 supply and deactivate rapidly.…”

Low‐dimensional amorphous metallic nanomaterials provide great possibility for creating high‐performance electrocatalysts owing to their conspicuous reacting merits derived from the flexible coordination structures, but remain extremely challenging in synthesis. Herein, this work reports a facile synthesis of carbon‐loaded amorphous 1.5‐nm‐thick Pt–Ru nanowires (NWs) through a local oxidation induced amorphization process. During annealing premade crystalline Pt–Ru NWs/C in air, a local‐oxidation of the oxyphilic Ru generates abundant random Ru–O bonds and disturbs the order bimetallic lattices. The as‐prepared amorphous Pt53Ru47 (a‐Pt53Ru47) NWs/C exhibits an extremely high activity (13.7 A mg−1 at 25 mV overpotential) and an excellent CO‐tolerance for alkaline hydrogen oxidation reaction (HOR) electrocatalysis, drastically outperforming the crystalline counterpart and commercial benchmarks. Mechanism studies indicate the Pt–Ru bimetallic effects as well as the rich disordered “Pt–Ru–O” and/or “Pt–O–Ru” atomic heterojunctions can weaken the *H binding energy and inversely strengthen the *OH adsorption, thus promoting the alkaline HOR kinetics. More uniquely, the small interatomic spaces derived from the disordered bond nets present a H2/*H‐selected permeability, which spatially obstruct the relatively larger CO molecules to poison the internal catalytic sites during HOR. The CO‐shielded internal catalytic sites and the enriched surface *OH jointly upgrade the CO‐tolerance of the a‐Pt53Ru47 NWs/C catalysts.

“…Interestingly, it has also been reported that the introduction of Mo atoms into Pt-based catalysts can reduce the energy barrier of water molecule dissociation and optimize the adsorption strength of the reaction intermediate H* on the Pt sites, thus enhancing the HER activity of the catalysts.

Constructing efficient and stable catalysts is the key to achieving green hydrogen production through electrolysis of water. Atomically dispersed catalysts have received widespread attention due to their high atomic utilization and catalytic efficiency. Herein, Pt1Mo1 dual‐atom catalysts anchored on the nickel selenide nanoisland (Pt1Mo1/Ni3Se2) are prepared by a two‐step method. It only needs 53 mV to deliver the current density of 10 mA cm−2 in 1 M KOH media, and the mass activity at 200 mV is approximately 4.13 times higher than that of Pt/C. In addition, the Pt1Mo1/Ni3Se2 also exhibits electrochemical stability of nearly 60 h at 20 mA cm−2. It is shown in the studies that the synergistic effect between Pt and Mo atoms enables the migration of electrons around Mo atoms toward Pt, thus realizing charge redistribution. Further density functional theory calculations verify that synergistic effect of Pt and Mo atoms could optimize the adsorption of H*, enhancing the hydrogen evolution reaction activity. Moreover, the Ni3Se2 nanoisland prevents the aggregation of Pt and Mo dual atom, effectively improving the stability of the catalyst. In this work, a nanoisland confined strategy is provided to construct atomically dispersed catalysts with high activity and stability for water splitting.
