Lamellar precursor materials have been heavily investigated for their use in creating carbon dioxide absorbents for industrial applications[1–4]. Synthesis of silica pillared MCM-36 demonstrated successful pillaring of microporous layers for carbon dioxide capture[5]. Subsequent research has focused on various metal oxide pillars to increase the chemical functionality and surface area of the support[6–8]. Using titanium oxide pillars, we have demonstrated an MCM with higher CO₂ capture capacity than silica MCM sorbent, despite a lower surface area. Despite a chemical reaction with the MCM structure, complete desorption of CO₂ was observed under inert gas flow at room temperature. In addition, based off of alternative tests, it may be possible to synthesize a Ti-MCM-36 solid with increased surface area, thereby increasing the overall CO₂ capture capacity compared to previous MCM materials.
