Abstract

In this study, nanoporous Cu₃(BTC)₂ membranes were synthesized on macroporous alumina tube supports by solvothermal method. It is very difficult to prepare uniform and crack-free Cu₃(BTC)₂ layer on macroporous alumina support by in situ solvothermal method. In this study, continuous and crack-free Cu₃(BTC)₂ tubular membranes could be obtained by in situ solvothermal process after surface modification of alumina support. The surface modification was conducted by spraying Cu precursor solution on the alumina support heated at 200 oC. The prepared Cu₃(BTC)₂ tubular membranes were characterized by XRD, FE-SEM and gas permeation experiments. H₂ permeance through 5 μm thick Cu₃(BTC)₂ tubular membrane was calculated to be 7.8×10 mol/s·m ·Pa by single gas permeation test, with the ideal selectivities of H₂/N₂=11.94, and H ₂/CO₂=12.82.
