“…After cooling to room temperature, the self‐luminous wood was obtained. [ 231 ] The prepared composite had a relatively high latent heat of fusion (146.7 J g −1 ) and a phase change temperature of ≈37 °C. Furthermore, it could absorb ultraviolet and visible light, which emits the green light up to 11 h in dark.…”

performance environmentally friendly materials. This is because new processes will be required that allow control on all hierarchical levels. Wood is well defined as a biological engineering material with a complex hierarchical structure of organic material based on cellulose fibrils embedded in a matrix of hemicelluloses and lignin. [1,2] Wood has long been used as a construction material, as well as for pulp and paper production. These applications are highly dependent on the properties of lignin in wood. Removal of lignin is the key step in pulp and paper production, in addition to the conversion of biomass to liquid biofuels. Lignin was first discovered in wood by Anselme Payen in 1839, [3] as the incrusting material that must be removed to isolate the useful fibers in wood. Research pertaining to wood nanotechnology or functional wood materials is a rapidly emerging field. Functional wood materials are mostly fabricated by treating hierarchical natural templates (wood cell wall) by chemical and thermal means. These treatments selectively modify the wood cell wall structure (fine pore spaces and inner lumen surface area) for different applications. [4] The pore region and inner lumen surface have actively been modified to enhance the bulk properties of wood using organic chemicals, [5] inorganic chemicals, organic-inorganic chemicals, [6,7] and thermal methods. [8] Hybrid wood scaffolds have been prepared for diverse applications such as magnetic wood, [9,10] as well as wood-mineral and wood-metal hybrids. [11] Recent research on delignified wood (DW) has emerged from the classical pulp production method. In the preparation of DW, the embedded lignin is removed from the wood cell wall structure, while maintaining the natural hierarchical cellulosic structure. [12] Initially, DW was prepared in order to understand the unknown ultrastructure of wood cell walls. However, since 2015, research in this area has rapidly expanded to focus on the development of wood-based functional scaffolds. Within the literature, DW is predominantly prepared using alkaline delignification methods such as Kraft pulping (a mixture of sodium hydroxide (NaOH) and sodium sulfite (Na 2 SO 3 )) heated to boiling temperature), followed by bleaching using hydrogen peroxide (H 2 O 2 ) to remove the lignin. DW is chemically hydrophilic due to the presence and exposure of hydroxyl groups and possible sites for DW functionalization. DW scaffolds have been functionalized

Using an inexpensive and eco-friendly wood substrate, herein, a one-step calcination method is developed to deposit Co-Ni binary nanoparticles into aligned wood channels and an effective carbonized wood (CW) electrode (termed as Co/Ni-CW) is fabricated. Well distributed Co-Ni nanoparticles are achieved by the coordination bonds between the hydroxyl groups on wood matrix and soaked metal cations. Subsequently, high-temperature calcination promotes the nucleation of Co-Ni nanoparticles and the formation of CW. With the uniform distribution of Co-Ni nanoparticles and porous wood structure, not only is a high active surface area, but also the electron and mass diffusion pathways are enhanced. Thus, the as-prepared Co/Ni-CW affords the current density of 10 mA cm -2 at low overpotentials of 330 and 157 mV for oxygen and hydrogen evolution, respectively. Remarkably, when the wood-based bifunctional electrocatalyst is used as both the anode and cathode, a low cell voltage of 1.64 V is required to reach the current density of 10 mA cm -2 . Compared with most substrates used in bifunctional electrocatalysts, the abundance, low cost, eco-friendliness, and easy operation of woodbased catalysts allow for an active and scalable electrode for water splitting and many other energy storage devices.
