Bu çalışmada, saf silika kaynağından üretilen mezogözenekli silika MCM-41’in yüzeyi aşılama yöntemiyle amin grupları ile fonksiyonelleştirilmiştir. Fonksiyonelleştirilen ürünün karakterizasyonu X-ışınları difraktometresi (XRD), termogravimetri/diferansiyel termal analiz (TG/DTA), Fourier dönüşümlü infrared spektroskopisi (FTIR) ve Brunauer-Emmett-Teller (BET) cihazında gerçekleştirilmiştir. Fonksiyonelleştirilen ve fonksiyonelleştirilmemiş MCM-41 adsorbanlarının CO₂ adsorpsiyon kapasiteleri 25, 75 ve 100°C’de TG/DTA cihazı ile belirlenmiştir. Sonuç olarak, fonksiyonelleştirilen MCM-41’in daha yüksek CO₂ adsorpsiyon kapasitesine sahip olduğu görülmüştür.
