“…Garemark et al [ 11 ] used an ionic liquid mixture to prepare strong shape-memory bio-aerogels from natural balsa, birch, ash, and spruce. He et al [ 18 ] used nanotechnology and carboxylated functionalization treatment approaches to create an eco-friendly, tunable, dual-wavelength absorption mesoporous balsa WA. These results paved the way for research on aerogels derived from agroforestry biomass.…”

The construction of networks within natural wood (NW) lumens to produce porous wood aerogels (WAs) with fascinating characteristics of being lightweight, flexible, and porous is significant for the high value-added utilization of wood. Nonetheless, how wood species affect the structure and properties of WAs has not been comprehensively investigated. Herein, typical softwood of fir and hardwoods of poplar and balsa are employed to fabricate WAs with abundant nanofibrillar networks using the method of lignin removal and nanofibril’s in situ regeneration. Benefiting from the avoidance of xylem ray restriction and the exposure of the cellulose framework, hardwood has a stronger tendency to form nanofibrillar networks compared to softwood. Specifically, a larger and more evenly distributed network structure is displayed in the lumens of balsa WAs (WA-3) with a low density (59 kg m−3), a high porosity (96%), and high compressive properties (strain = 40%; maximum stress = 0.42 MPa; height retention = 100%) because of the unique structure and properties of WA-3. Comparatively, the specific surface area (SSA) exhibits 25-, 27-, and 34-fold increments in the cases of fir WAs (WA-1), poplar WAs (WA-2), and WA-3. The formation of nanofibrillar networks depends on the low-density and thin cell walls of hardwood. This work offers a foundation for investigating the formation mechanisms of nanonetworks and for expanding the potential applications of WAs.

“…Furthermore, wood is an excellent carbon-based template for in situ loading of functional micronanoparticles. Wen He et al developed an eco-friendly tunable dual-wavelength adsorption mesoporous wood aerogel, whose adsorption capacity for Cu(II) was 115 mg/g . Pang et al proposed a natural wood (NW)-derived catalyst comprising wood carbon and Fe/Co sites as an activator for PMS and achieved a 100% removal rate for ciprofloxacin in 4 min CdS is a typical n-type semiconductor with a band gap of only ∼2.4 eV, which enables it to exhibit satisfactory light absorption properties under visible light, resulting in excellent separation efficiency of photogenerated carriers .…”

Pollutant treatment, hazardous solid waste conversion, and biomass resource utilization are significant topics in environmental pollution control, and simultaneously achieving them is challenging. Herein, we developed a "from waste absorbent to effective photocatalyst" upcycle strategy for nontoxic conversion of Cd(II) adsorbed on thiolation@wood-aerogel (TWA) into CdS/g-C 3 N 4 heterojunctions through the in situ chemical deposition high-temperature carbonization combined conversion method to overcome the above problems simultaneously. We used Schiff base reaction to graft L-cysteine into dialdehyde@woodaerogel to prepare TWA with a high Cd(II) adsorption capacity (600 mg/L, 294.66 mg/g). Subsequently, the spent Cd(II)-loaded-TWA was used as a substrate for in situ construction of Cd(II) into CdS/g-C 3 N 4 heterojunction for activating peroxymonosulfate (PMS) under simulated sunlight [simulated solar light (SSL)], achieving efficient tetracycline (TC) degradation (20 mg/L, 95.32%). The Langmuir and pseudo-second-order models indicate single-layer chemical adsorption of Cd(II) on the TWA adsorption process. In the PMS/SSL system, CdS/g-C 3 N 4 @TWA efficiently and rapidly degraded TC via an adsorption-photocatalytic synergistic degradation mechanism. The used CdS/g-C 3 N 4 @TWA has a good biocompatibility. This study proposed design and preparation of a new type of wood aerogel absorbent and provided a novel upcycling strategy for innovative use of the spent waste adsorbent.
