摘要

由于海水资源丰富，海水电解制氢技术受到了世界各国的广泛关注。在此，我们提出了以α/β-MnO2纳米线为核心，无定形Ru为外壳的核壳Ru@MnO2纳米线，其中Ru@α- mno2纳米线具有较低的过电位和较好的稳定性。更重要的是，它们可以作为双功能催化剂稳定运行250 h以上，并且在太阳能驱动下保持优异的催化性能。

Ru@MnO₂ core@shell nanowires as a bifunctional electrocatalyst for efficient solar-driven seawater splitting.

Seawater electrolysis technology for hydrogen production has attracted worldwide attention due to the abundant seawater resources. Herein, we proposed core-shell Ru@MnO₂ nanowires (NWs) with α/β-MnO₂ NWs as the core and amorphous Ru as the shell, in which the Ru@α-MnO₂ NWs exhibited lower overpotential and better stability. More importantly, they can operate stably as a bifunctional catalyst for more than 250 h and maintain excellent catalytic performance when driven by solar energy.
