Fabrication of Wood-Derived Carbon Aerogel/Mg(OH)2 Bio-Composite and Its High Performance for Adsorption and Separation of Cadmium Ions

C – Journal of Carbon Research, Journal Year: 2025, Volume and Issue: 11(2), P. 32 - 32

Published: May 6, 2025

: To address the need for reducing carbon emissions and enhancing sustainable utilization of non-fossil resources, a one-step calcination strategy has been developed to fabricate hierarchical aerogels from balsa wood. The resulting wood-derived (WCA) were functionalized with Mg(OH)2 boost their environmental remediation potential. Comprehensive characterization using XRD, FT-IR, XPS, SEM confirmed that optimized WCA/Mg(OH)2 composite (WCAMg) retained three-dimensional porous structure, nanosheets attached it. adsorption performance WCAMg composites towards Cd2+ was systematically investigated through controlled experiments, which focused on three critical variables (Mg(OH)2 loading content, initial concentration solution ionic strength). demonstrated maximum capacity 351.1 mg g−1—a tenfold improvement over pristine WCA. Combined exceptional efficiency, this biomass-derived offers an eco-friendly, cost-effective heavy metal ion remediation. Its scalable fabrication renewable resources aligns water treatment objectives, presenting advantage pollution mitigation.
