Abstract: [Display omitted] • Novel NiCo-LDH/CoFcDCA heterostructure boosts OER & UOR. • Ultrathin NiCo-LDH enable efficient charge transfer via heterointerfaces. • Optimized Ni/Co ratio achieves high bifunctional activity and stability. • Strategy guides design of heterointerface-rich electrocatalysts. The development of efficient and durable non-precious electrocatalysts for water splitting is crucial for sustainable hydrogen production. Herein, we report a novel NiCo-LDH/CoFcDCA heterostructure synthesized via a hydrothermal-electrodeposition method, which demonstrates exceptional catalytic performance for both oxygen evolution reaction and urea oxidation reaction. The ultrathin NiCo-LDH nanosheets (∼15 nm) grown on conductive CoFcDCA/NF substrate create abundant heterointerfaces that facilitate electron transfer and optimize reaction energetics. Through systematic optimization of the Ni/Co ratio, the catalyst achieves outstanding activity, while maintaining excellent long-term stability. This work not only presents a high-performance bifunctional electrocatalyst but also provides a general strategy for constructing advanced heterointerface-rich materials for energy conversion applications.
