CuCo-Layered Double Hydroxide Nanosheets Grown on Hierarchical Carbonized Wood as Bifunctional Electrode for Supercapacitor and Hydrogen Evolution Reaction.

ABSTRACT: Carbonized wood has great potential as a self-supported electrode for energy storage/conversion applications. However, developing efficient and economical bifunctional electrodes by customizing the surface structure remains a challenge. This study proposes a novel multifunctional electrode design strategy, using N/P co-doped carbonized wood (NPCW) as carriers and in situ grows copper nanoparticles (Cu NPs) as nucleation centers to induce vertical growth of CuCo-layered double hydroxid (LDH) nanosheets along the substrate. This method avoids the disordered stacking of catalysts and forms the "carbon-metal-LDH" tertiary conductive network. Therefore, the hierarchical CuCo-LDH@Cu/NPCW is successfully fabricated. Benefiting from the hierarchical ultrathin nanosheet arrays and the strong electr
