The efficient mass transport and enhanced accessibility of active sites are crucial for high-performance electrocatalysts in water splitting. Inspired by the hierarchical structure natural wood, we engineered a monolithic electrocatalyst, cobalt nanoparticles encapsulated nitrogen-doped carbon layers on carbonized wood (Co@NC/CW), carbonizing to create three-dimensional framework with vertically aligned macropores. unique architecture encapsulates within situ-grown graphene wood-derived microchannels, facilitating ultrafast electrolyte infusion anisotropic electron transport. As result, optimized freestanding Co@NC/CW electrode exhibits remarkable bifunctional activity, achieving overpotentials 403 mV 227 oxygen evolution reaction (OER) hydrogen (HER), respectively, at current density 50 mA cm−2. Furthermore, integrated hybrid electrolyzer combining HER OER delivers an impressive A cm−2 cell voltage 1.72 V while maintaining Faradaic efficiency near 99.5% sustaining long-term stability over 120 h continuous operation. also demonstrates performance complete decomposition alkaline seawater, underscoring its potential scalable applications. This catalyst design not only leverages porosity but offers sustainable platform advanced electrochemical systems.
