A hydrogen permeation membrane is provided that can include a carbon-based material (C) and a ceramic material (BZCYT) mixed together. The carbon-based material can include graphene, graphite, carbon nanotubes, or a combination thereof. The ceramic material can have the formula BaZrCeYTO, where 0&#x2264;x&#x2264;0.5, 0&#x2264;y&#x2264;0.5, 0&#x2264;z&#x2264;0.5, (x+y+z)&#x3e;0; 0&#x2264;&#x3b4;&#x2264;0.5, and T is Yb, Sc, Ti, Nb, Ta, Mo, Mn, Fe, Co, Ni, Cu, Zn, Ga, In, or a combination thereof. In addition, the BZYCT can be present in the C-BZCYT mixture in an amount ranging from about 40% by volume to about 80% by volume. Further, a method of forming such a membrane is also provided. A method is also provided for extracting hydrogen from a feed stream.

Graphene-ceramic composite membrane for hydrogen separation membranes

A method for generating hydrocarbons using a solid oxide electrolysis cell (SOEC) and a Fischer-Tropsch unit in a single microtubular reactor is described. This method can directly synthesize hydrocarbons from carbon dioxide and water. The method integrates high temperature co-electrolysis of HO and COand low temperature Fischer-Tropsch (F-T) process in a single microtubular reactor by designation of a temperature gradient along the axial length of the microtubular reactor. In practice, methods disclosed herein can provide direct conversion of COto hydrocarbons for use as feedstock or energy storage.
