효율적인 CO2 흡착 용량을 갖춘 지속 가능한 소나무 솔방울 바이오차 합성

Synthesis of Sustainable Pinus Cone Biochar with Efficient CO₂ Adsorption Capacity

초록

This study investigates Pinus cone-derived biochar as a sustainable CO2 adsorbent. Prepared at 500 °C and activated with KOH, the biochar exhibits a BET surface area of ~28 m²/g and an average pore diameter of 13.52 Å. CO2 adsorption reaches 30.45 cm³/g at 273 K and 1 bar. The enhanced performance is attributed to its microporous structure and surface functional groups. These findings highlight the potential of low-cost, eco-friendly biochar for effective CO2 capture and environmental sustainability.
