Synthesis and Characterization of EDTA-Bridged Periodic Mesoporous Organosilica for Enhanced CO۲ Adsorption

The increasing concentration of carbon dioxide (CO۲) in the atmosphere has become a critical environmental concern due to its major contribution to global warming and climate change. Developing efficient, stable, and recyclable adsorbents for CO۲ capture is therefore of great importance. In this study, a novel ethylenediaminetetraacetic acid-bridged periodic mesoporous organosilica (EDTA-PMO) was synthesized through a sol-gel co-condensation route using tetraethyl orthosilicate (TEOS) and an EDTA-bridged organosilane precursor under surfactant-templated conditions.
