Abstract

Calcium hydroxide (Ca(OH) ₂ ) has been proposed as an important material for industrial, architectural, and environmental applications. In this study, calcium acetate was used as a precursor and cetyl trimethyl ammonium bromide (CTAB) was used as a surfactant to synthesize Ca(OH) ₂ based adsorbents for carbon dioxide (CO ₂ ) capture. The effect of CTAB concentration (0.2-0.8 M) on the structure, morphology and CO ₂ adsorption performance of Ca(OH) ₂ was studied in detail. The synthesized samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), BET surfaced area and thermogravimetry-differential thermal analysis (TG-DTA) techniques. The phase purity, crystallite size, Brunauer-Emmett-Teller (BET) surface area and CO ₂ adsorption performance of Ca(OH) ₂ precursor adsorbents were significantly increased when the concentration of CTAB was increased. XRD results showed that pure Ca(OH) ₂ phase was obtained at the CTAB concentration of 0.8 M. TGA results exhibited that 0.8 M of CTAB-assisted Ca(OH) ₂ precursor adsorbent possessed a residual carbonation conversion of ∼56% after 10 cycles.
