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 mA·cm−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.
