Amorphous and outstandingly stable Ni(OH)2·0.75H2O@Ni(OH)2/FeOOH heterojunction nanosheets for efficient oxygen evolution performance

Amorphous Ni(OH) 2 ·0.75H 2 O@Ni(OH) 2 /FeOOH heterojunction nanosheets with enhanced OER catalytic activity were synthesized. The introduction of Fe effectively regulated the electronic structure of Ni, improving the catalyst performance.
