Synthesis of discrete SSZ-39 zeolite nanosheets by solvent-free seed-assisted route for efficient CO2 capture
Efficient CO2 capture from flue gas and natural gas is highly desirable to reduce greenhouse gas emissions. Discrete SSZ-39 zeolite nanosheets are prepared by the solvent-free seed-assisted route for the first time to capture CO2. Synthesis parameters such as H2O/SiO2 ratio and synthesis time are optimized and the formation mechanism of the SSZ-39 zeolite nanosheets is studied. The nanosheets have a thickness of 30 nm and an aspect ratio of 10. The HR-TEM characterization shows that the base face of the nanosheet corresponds to its (001) plane with a pore size of 3.8 Å × 3.8 Å. The CO2/N2 and CO2/CH4 selectivities of SSZ-39 zeolite nanosheets are as high as 1092 and 136 by Ideal Adsorption Solution Theory (IAST), respectively. Furthermore, breakthrough results indicate that SSZ-39 zeolite nanosheets have great application potential for separating CO2 from flue gas and natural gas.
期刊介绍:
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
