Development of H2-permselective membrane with hydrothermal stability

The doping of Ni to ・-Al_2O_3 and the introducing of Si-O-Si bond to Si raw material are very effective to improve hydrothermal stability in H_2-permselective membrane. The degradation of hydrogen permselectivity was caused by both the densification of amorphous silica network and the increasing of pore size in ・-Al_2O_3 during hydrothermal exposure. The development of mesoporous intermediate layer with high hydrothermal stability is more important to improve hydrothermal stability in H_2-permselective membrane.
