A well-developed porous structure and ultrahigh surface area of porous carbons are essential for challenging the gas adsorption. Herein, we synthesized biomass-based porous carbon with a facile and effectively adjustable pore structure. The maximum surface area of activated carbon is up to 3839 m 2 g −1 , and high micropores and narrow mesopores (1.94 mL g −1 with d < 3 nm) are obtained. The tailored porous carbons are extensively applied in the energy and environment fields, such as their improved acetone adsorption, CO 2 capture, and light hydrocarbon separation. The porous carbon exhibits record-high acetone (i.e., 26.2 mmol•g −1 at 18 kPa and 25 °C) and CO 2 uptake (i.e., 29.5 mmol•g −1 at 30 bar and 25 °C) among reported carbons at relative high pressure. Besides, the UC800 exhibits superior C 2 H 6 and C 3 H 8 uptake of 7.19 and 12.02 mmol•g −1 , respectively. The C 2 H 6 /CH 4 and C 3 H 8 /CH 4 selectivity of the UC800 are up to 9.1−14.6 and 41.8−63.2, respectively. The simple method can open the door to design and develop highly porous carbons with a desired porous structure for the gas adsorption application.

We used an innovative approach involving hot pressing, low energy consumption, and no adhesive to transform bamboo biomass into a natural sustainable fiber-based biocomposite for structural and furniture applications. Analyses showed strong internal bonding through mechanical “nail-like” nano substances, hydrogen, and ester and ether bonds. The biocomposite encompasses a 10-fold increase in internal bonding strength with improved water resistance, fire safety, and environmentally friendly properties as compared to existing furniture materials using hazardous formaldehyde-based adhesives. As compared to natural bamboo material, this new biocomposite has improved fire and water resistance, while there is no need for toxic adhesives (mostly made from formaldehyde-based resin), which eases the concern of harmful formaldehyde-based VOC emission and ensures better indoor air quality. This surpasses existing structural and furniture materials made by synthetic adhesives. Interestingly, our approach can 100% convert discarded bamboo biomass into this biocomposite, which represents a potentially cost reduction alternative with high revenue. The underlying fragment riveting and cell collapse binding are obviously a new technology approach that offers an economically and sustainable high-performance biocomposite that provides solutions to structural and furniture materials bound with synthetic adhesives.

To reuse lignin polymers from bioethanol biorefinery plants, wood/lignin composites (WLC) were modified by mold pressing, processed, and analyzed using X‐ray diffractometry, Fourier transform‐infrared spectroscopy, thermogravimetric analysis, and thermal desorption‐gas chromatography‐mass spectrometry. With increased temperature and time, cellulose, hemicellulose, and lignin increased the thermal degradation reaction and generated many extracts. Comprehensive analysis of the analytical results suggested that mold pressing at 160°C or 220°C for 20 min was optimal for WLC preparation. However, care should be taken as the volatiles included acetic acid, phenol and its derivatives, and benzene and its derivatives, which are toxic. POLYM.
