The large-scale integration of wind or photovoltaic power into the power grid has led to significant wastage of wind and photovoltaic resources. Directly producing hydrogen using renewable energy sources is one of the effective ways to absorb abandoned light and wind. Here, we report a novel self-supporting metallic glass (MG) electrode. This self-supporting electrode exhibits excellent hydrogen evolution reaction (HER) performance with a very small overpotential of 30.16 mV at 10 mA cm–2 in acidic media after controllable electrochemical treatment (CET). The CET metallic glass also demonstrates robust HER catalytic performance and stability under fluctuating power condition. At a consistent overpotential, the current density increased from 1000 to 1366 mA cm–2 within 200 h and then remained stable for over 200 h even at high current densities. The remarkable catalytic performance, excellent durability, and self-supporting nature of the metallic glass electrode make it highly promising for green hydrogen production. Directly producing hydrogen using this material will effectively utilize wasted wind and photovoltaic resources, contributing to achieving global carbon neutrality.

自支撑金属玻璃作为波动可再生能源下高度耐用的 HER 电极
风电或光伏发电的大规模并网，导致风电和光伏资源的严重浪费。利用可再生能源直接制氢是吸收废弃光和风的有效方法之一。在这里，我们报告了一种新型自支撑金属玻璃（MG）电极。这种自支撑电极表现出优异的析氢反应（HER）性能，经过可控电化学处理（CET）后，在酸性介质中，10 mA cm –2下的过电位仅为 30.16 mV。 CET 金属玻璃还表现出强大的 HER 催化性能和波动功率条件下的稳定性。在一致的过电势下，电流密度在 200 小时内从 1000 mA cm –2增加到 1366 mA cm –2 ，然后即使在高电流密度下也能保持稳定超过 200 小时。金属玻璃电极卓越的催化性能、优异的耐用性和自支撑性质使其在绿色制氢方面具有广阔的前景。利用这种材料直接制氢将有效利用废弃的风能和光伏资源，为实现全球碳中和做出贡献。
