摘要：
Microwave energy absorbed by biochar carbonized the impregnated lignin to increase micropore structure.CO2 uptake on lignin-impregnated biochar reached 134.46 mg g−1 and was associated with micropore, alkalinity, and temperature.CO2 adsorption on lignin-impregnated biochar was governed by physisorption with slight chemisorption.Lignin-impregnated biochar demonstrated excellent reusability and selectivity in CO2 capture.
