Although tremendous efforts have been paid on electrocatalysts toward efficient electrochemical hydrogen generation, breakthrough is still highly needed in the design and synthesis of wonderful non-precious-metal electrocatalyst. Herein, a nanovilli Ni₂P electrode, which with superaerophobic and superhydropholic can significantly facilitate the mass and electron transfer was constructed via a facial morphology control strategy. Meanwhile, the substitution of sluggish oxygen evolution with urea oxidation, lowering the two-electrode cell voltage to only 1.48 volts to achieve a current density of 10 mAcm⁻². Thus, the as-constructed electrode achieves the operation of hydrogen generation by an AA battery. This work sheds new light on the exploration of other high-efficient electrocatalysts for hydrogen generation by using intermittent clean energy.

尽管已经在电催化剂上进行了巨大努力以有效地产生电化学氢，但是在设计和合成优异的非贵金属电催化剂方面仍需要突破。在此，通过面部形态控制策略构建了具有超疏水性和超疏水性的纳米绒毛Ni ₂ P电极，该电极可显着促进质量和电子转移。同时，用尿素氧化代替缓慢的氧气释放，将两电极电池电压降低到仅1.48伏，以实现10 mAcm ^-2的电流密度。因此，如此构造的电极实现了通过AA电池产生氢的操作。这项工作为探索其他使用间歇性清洁能源生产氢气的高效电催化剂提供了新的思路。
