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 COcapture capacity compared to previous MCM materials.
