Abstract
- 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 Ni<subscript>2</subscript>P 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<superscript>−2</superscript>. 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. [ABSTRACT FROM AUTHOR]
