| 英文摘要 | It is challenging to directionally construct the amorphous/crystalline (a/c)-alloy/oxide heterostructures with exceptional bifunctional electrocatalytic performances via a facile method. With these in mind, the a/c-RuCo NWs/NF electrode with the unique hollow structure and a/c-Co0.8Ru0.2/RuCoOx heterostructure was constructed by cleverly controlling the corrosion time. As expected, the well-designed a/c-RuCo NWs/NF||a/c-RuCo NWs/NF only needs 1.46 V to reach an industrial-grade current density of 1 A cm- 2, outperforming other advanced electrodes. Strikingly, density functional theory (DFT) and in-situ Raman reveal that the Ru delta+-Ru0 dual-sites and Co delta+ at the a/c-Co0.8Ru0.2/RuCoOx heterointerface act as active species for alkaline HER and UOR, synergistically promoting urea-assisted water splitting. Surprisingly, the unique Co0.8Ru0.2 alloy exhibits the potential to surpass the pure Ru metal in optimizing d-band centers and the adsorption of reaction intermediates. Overall, the a/c-alloy/oxide bifunctional electrode with Ru delta+-Ru0-Co delta+ multi-active sites was constructed by one-step corrosion, providing a new idea for designing efficient a/c-alloy/oxide electrodes and realizing industrial urea-assisted water splitting. |
