Rh-modified alumina membranes: preparation, characterization and reaction studies

Separation Performance of Nanoporous Carbon Membranes Fabricated by Catalytic Decomposition of CH4 Using Ni/Polyamideimide Templates

“…1.3 cm, i.d. 0.9 cm, length 30 cm, pore diameter 0.8−1 μm, porosity 30%; from Zhibo Ceramic Co. Ltd, China), were modified by repeated dip-coating in a boehmite (γ-AlOOH) sol . The membrane tubes were dried at room temperature (RT) for 24 h and calcined at 500 °C for 5 h after each dip-coating process.…”

Inorganic membranes for pre-combustion carbon dioxide (CO 2 ) capture

“…The hydrogen permeation characteristics of the porous support can be signifi cantly changed by depositing metal, for example Pd (Chen et al, 2003) or Rh (Liu et al, 1999), on the surface or in the pore structure of the support . For example, Kikuchi et al (2000) prepared a CVD platinum on a commercially available alumina tube with an average pore size of 200 nm which showed H 2 /N 2 selectivity as high as 280 and excellent performance similar to the electroless-plating palladium membrane.…”
