摘要：

In this study, we present a general and efficient strategy to design and prepare novel MOF-based hybrid membranes on a tubular ceramic substrate. Thin and compact MOF/organosilica nano-composite membranes can be rationally formed and tightly bound with the tubular ceramic substrate. The resulting membranes display high gas separation performance with both high selectivity and high permeation rate, which can be well correlated to the parent MOFs. The as-prepared ZIF-8 and MIL-53-NH2 incorporated organosilica nanocomposite membranes have been demonstrated as some of the best performing MOF-based membranes for highly H-2-(H-2/CH4 selectivity = 26.5, H-2 permeance = 1.06 x 10(-6) mol m(-2) s(-1) Pa-1) and CO2-selective (CO2/CH4 selectively = 18.2, CO2 permeance = 1.44 x 10(-7) mol m(-2) s(-1) Pa-1) separations, for H-2/CH4 (1 : 1) and CO2/CH4 (1 : 1) mixtures at room temperature, respectively.
