Abstract
In this communication, the copper net supported Cu3(BTC)2 membranes have been successfully synthesized by means of a “twin copper source” technique. Separation studies on gaseous mixtures (H2/CO2, H2/CH4, and H2/N2) using the membrane revealed that the membrane possesses high permeability and selectivity for H2 over CO2, N2, and CH4. Compared with the conventional zeolite membranes, the copper net supported Cu3(BTC)2 membrane exhibited high permeation flux in gas separation. Such highly efficient copper net supported Cu3(BTC)2 membranes could be used to separate, recycle, and reuse H2 exhausted from steam reforming natural gas.Keywords
