The most promising methods for high purity hydrogen production are membranes separation such as polymer, metal, ceramic and cermet. It is well known that Pd and Pd-alloy membranes have excellent properties for the hydrogen separation. However, it has hydrogen embrittlement and high cost for practical applications. Therefore, most of the scientists had searched about new materials instead of Pd and Pd-alloys. On the other hand. TiN powders are great in resistance to acids and chemically steady under high operation temperature. It had used in catalysts and fuel cell electrode application. The graphene had known new materials which have a high electro-conductivity and oxidation resistance. It was a good catalyst and thus big issue material. In accordance, fabrication of TiN-graphene membrane was prepared disk type of ceramic dense membrane by hot press sintering (HPS) process. TiN-graphene membrane was characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). TiN-graphene membrane was estimated hydrogen permeability by Sievert's type hydrogen permeation membrane equipment. (C) 2012 Elsevier B.V. All rights reserved.
