Mesostructured Zeolites Prepared by One-Pot Top-Down Synthesis Route for Carbon Dioxide Adsorption

With the increasing emphasis on circular economies, biogas has gradually become an important energy source, but the refinement of biogas to reduce CO2 concentrations and impurities is required. This study reports on a one-pot top-down route to easily obtain mesostructured zeolite for CO2 adsorption during the biogas refinement process. Combining surfactants with an acid/base treatment achieved a perforation effect and generated mesopores in the zeolite structure. The zeolite structure and the presence of mesopores in the material were confirmed via XRD and a pore-size distribution analysis.div>
