Nanocsrystals of Zn(pyrz)2(SiF6) (or SIFSIX-3-Zn) metal-organic framework were synthesized by a facile sonochemical means and incorporated into a polyimide membrane to realize an excellent CO2/CH4 separation performance. Zn(pyrz)2(SiF6) nanocrystals selectively took up a large amount of CO2 even at...
