Abstract: Hydrogen selective membranes and related methods are generally described. In some embodiments, a hydrogen selective membrane may exhibit high permeance and selectivity in comparison to conventional polymer membranes, at low material costs. The membrane may also be thermally and chemically stable at high operational temperatures. In some embodiments, the membrane may include a layer of inorganic material (e.g., palladium) and a layer of atomically thin material (e.g., graphene) arranged on a porous substrate. The inorganic material may be arranged in a film-like or an isolated island-type architecture. In other embodiments, the inorganic material may be arranged within the pores of the porous substrate in an isolated plug-type fashion.
