“…The authors attributed F-wood's capability in enhancing solar steaming to the solar absorbance of the wood biochar component and the hydrophilicity of the wood component. [50] Yu et al [51] made a device called the carbonized wood-based solar steam generator (CWSG) based on the partially carbonized wood monolith for saltwater desalination. The design of the device is shown in Figure 18.…”

“…Ion concentrations of the condensed water are lower than the standard for drinking water set by the World Health Organization (WHO) and the United States Environmental Protection Agency (USEPA). [ 51 ] Under a solar intensity of 5 kW/m 2 , the desalination performance was further improved, due to the higher rate of water evaporation. The high performance was attributed to the unique structure of partially carbonized wood monolith, which provided high solar absorbance and efficient water transport.…”

Trees are crucial to humankind's survival, releasing the oxygen we breathe, growing the fruits we eat, and supplying wood to build and warm our shelters. Heating wood at 300 C-800 C with little or no oxygen creates wood biochar, a carbonaceous product. Wood biochar monoliths have a continuous carbon matrix and morphological features that resemble anatomical elements in a tree, including xylem and phloem, which transport water from the root and deliver sugars from leaves to individual cells. Structurally and chemically, monolithic wood biochar belongs to nanoporous carbons (NPCs) consisting of carbon nanotubes arrays and integrated graphene sheets. Researchers have extensively explored NPCs as functional materials for applications essential to sustainability, including electrical energy storage, water purification, and CO 2 capture. However, the lack of scalable manufacturing technology continues to hinder the large-scale utilization of NPCs despite their demonstrated superiority in enhancing materials performance. Derived from abundant woody biomass with simple processes, wood biochar monoliths offer a new opportunity for overcoming this limitation. This review documents recent progress in applying wood biochar monoliths in areas critical to sustainability, focusing on electrical energy storage and water purification. This progress has revealed the potential of monolith wood biochar as a greener, more cost-effective, and scalable NPC in enhancing sustainability and opened the door to a new field that is both exciting and relevant. The review concludes with a perspective on the future research direction.

Manufacturing a multilayer evaporator with a delicate structure and removing salt accumulation during prolonged operation are challenges in seawater desalination. A flexible single‐layer salt‐rejecting monolithic porous evaporator (SRMPE) is presented that floats on the near surface of seawater without any support structure. The hydrophilic component of this network polymer modulates the water association state in SRMPE, achieving a high evaporation rate of 3.47 kg m−2 h−1 and an efficiency of 94.3%. With a large capillary water flux (14.4 L m−2 h−1), the SRMPE exhibits superior and rapid self‐cleaning by removing sodium chloride (NaCl) powder (33% by weight) within 1.25 h in simulated seawater (salinity, 3.5%) under 1 sun radiation. Furthermore, even after continuous irradiation for 12 h in highly concentrated brine (25% salinity), no salt crystallizes on the evaporator surface. It may stimulate creative work by scientists and engineers in the design of simple, highly efficient salt‐rejecting, self‐cleaning interfacial solar evaporators.

Wood is a sustainable and renewable material that naturally has a hierarchical structure. Cellulose, hemicellulose, and lignin are the three main components of wood. The unique physical and chemical properties of wood and its derivatives endow them with great potential as resources to fabricate advanced materials for use in bioengineering, flexible electronics, and clean energy. Nevertheless, comprehensive information on wood‐derived carbon and light‐emitting materials is scarce, although much excellent progress has been made in this area. Here, the unique characteristics of wood‐derived carbon and light‐emitting materials are summarized, with regard to the fabrication principles, properties, applications, challenges, and future prospects of wood‐derived carbon and light‐emitting materials, with the aim of deepening the understanding and inspiring new ideas in the area of advanced wood‐based materials.
