Researchers from Leibniz University Describe Findings in Organosilica (Organosilica functionalized zeolitic imidazolate framework ZIF-90 membrane for CO2/CH4 separation)

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Organosilica are presented in a new report. According to news reporting originating in Hannover, Germany, by NewsRx journalists, research stated, "The separation of CO2/CH4 is reported by using 3-aminopropyltriethoxysilane (APTES) modified zeolitic imidazolate framework ZIF-90 membrane. The as-prepared ZIF-90 membrane was modified by APTES based on an imine condensation reaction between the free aldehyde groups of the ZIF-90 frameworks and the amino groups of APTES."

The news reporters obtained a quote from the research from Leibniz University, "After APTES modification, the morphology, purity and crystallinity of the ZIF-90 membrane keep unchanged. Attributing to both pore mouth narrowing and sealing of invisible intercrystalline defects of the polycrystalline ZIF-90 layer, the separation performances of the APTESmodified ZIF-90 membrane are remarkably enhanced."

According to the news reporters, the research concluded: "For the separation of equimolar CO2/CH4 mixture at 225 C and 1 bar, a CO2 permeance of 1.26 x 10(-8) mol m(-2) s(-1) Pa-1 and a CO2/CH4 selectivity of 4.7 are obtained, which is of promising in the potential application of CO2 separation and removal."
