due to several excellent advantages such as permeability improvement of the selective component, in addition to the enhancement of the thermal stability and the mechanical strength of a polymeric membrane, [17] and its molecular sieving property, thermal resistance and chemical stability [18,19,20]....
Sulfur hexafluoride (SF6) is a greenhouse gas with a global warming potential of 23900 times higher than CO2. It is essential to develop effective methods to separate and recover SF6 from spent gas to prevent its strong release into the atmosphere. Herein high-quality SSZ-13 zeolite membranes ...
Here we report that high‐performance hollow fiber membranes of the small‐pore (0.38?nm) zeolite SSZ‐13 can be produced via UV irradiation to decompose and remove the SDA. Remarkably, UV irradiation allowed complete removal of the bulky SDA (trimethyladamantylammonium hydroxide) from the pores ...
SSZ-13 membrane was prepared using oil-bath heating method. Significant reduction on synthesis time (from 2 to 6 d to 2 h) and membrane thickness (from 5 to 10 mu m-1.5 mu m) were realized, which is the result of enhanced nucleation and crystallization from ultrafast heat transfer of ...
