“…Wood, a natural and renewable resource from trees, possesses abundant porous structure and aligned microchannels for the penetration and diffusion of ions [28][29][30][31][32]. Carbonized wood can inherit original three-dimensional (3D) structures, which is considered as an ideal supporter for loading metal compounds and hold tremendous potential for applications in energy storage [33][34][35].…”

Multichannel-porous carbon derived from wood can serve as a conductive substrate for fast charge transfer and ion diffusion, supporting the high-theory capacitance of pseudocapacitive materials. Herein, NiCo2O4 nanosheets, which are hierarchically porous, anchored on the surface of carbonized wood via electrodeposition for free-binder high-performance supercapacitor electrode materials, were proposed. Benefiting from the effectively alleviated NiCo2O4 nanosheets accumulation and sufficient active surface area for redox reaction, a N-doped wood-derived porous carbon-NiCo2O4 nanosheet hybrid material (NCNS–NCW) electrode exhibited a specific electric capacity of 1730 F g−1 at 1 A g−1 in 1 mol L−1 KOH and splendid electrochemical firmness with 80% capacitance retention after cycles. Furthermore, an all-wood-based asymmetric supercapacitor based on NCNS–NCW//NCW was assembled and a high energy density of 56.1 Wh kg−1 at a watt density of 349 W kg−1 was achieved. Due to the great electrochemical performance of NCNS–NCW, we expect it to be used as an electrode material with great promise for energy storage equipment.

“…Due to increased focus on energy conservation and pollution reduction, wooden materials are widely used in various elds because wood is a renewable resource with an exceptional strength-to-weight ratio; however, the utilization of wooden materials during outdoor service is restricted by their lack of dimensional stability, low resistance to decay, and poor durability (Guo et al, 2015;Mastouri et al, 2021).…”

Thermal treatment can improve the dimensional stability of wood, but it also decreases wood's stiffness and increases its brittleness. In this paper, combining FTIR spectroscopy and mechanical analysis was used to in-situ study the molecular-level responses to stresses and analyze mechanical interactions among components in thermally-treated wood. For both untreated and treated woods, the cellulose was the longitudinal tensile load-bearing component of wood, but the lignin participated in the load transfer in the ber direction. Moreover, the FTIR results indicated that hemicellulose degradation, as the interface between cellulose and lignin, decreased shear slipping between micro brils. The interfacial material degradation also caused the wood's stiffness and mechanical responses of the matrix along the cell transverse direction decrease. Upon increasing the heat treatment intensity, the cellulose micro brils rearranged along the cell axis, resulting in the ability of the cell wall to resist deformation and the wood's stiffness being increased.

“…Hao et al ( 2021) examined moso bamboo samples of 300 mm × 30 mm × 8 mm (longitudinal × tangential × radial) in methyl silicon oil at 140 • C, 160 • C, 180 • C, and 200 • C for 2 h, 4 h, and 6 h, respectively, and showed that with increasing heat treatment temperature and time, there is a gradual decrease in the content of cellulose and hemicellulose while there is an increase in the relative content of lignin which is more thermally stable [64]. Mastouri et al, 2021, in their study investigated the effects of heat treatment using rapeseed oil and silicone oil on wood samples. The wood samples were taken from the sapwood of 30-year-old P. deltoides trees, the common name of which is the eastern cottonwood or necklace poplar, with the specific dimensions of 30 × 30 × 20 mm 3 (longitudinal × radial × tangential) and immersed in oil baths at room temperature and treated in a high-temperature oven for 4 h. When the temperature reached the 190 • C, the Fouriertransform infrared spectroscopy (FTIR) analysis revealed significant modifications in the chemical composition of the wood after treatment.…”

Wood, a natural material with versatile industrial applications, faces limitations such as low dimensional stability and decay resistance. To address these issues, there has been significant progress in wood modification research. Oil heat treatment has emerged as an effective method among environmentally friendly wood treatment options. Studies have indicated that treating wood with hot vegetable oils yields superior properties compared to traditional methods involving gaseous atmospheres, which is attributed to the synergistic effect of oils and heat. This comprehensive review investigates the physical, chemical, and mechanical modifications induced by the oil heat treatment of wood, along with its impact on biological durability against biotic agents. The review synthesizes recent research findings, elucidates underlying mechanisms, and discusses the implications for wood material science and engineering.
