VANADIUM-BASED ALLOY HYDROGEN SEPARATION MEMBRANE DOPED WITH YTTRIUM, AND HYDROGEN SEPARATION METHOD USING SAME

摘要

Provided are a vanadium-based alloy hydrogen separation membrane doped with yttrium, and a hydrogen separation method using same. The hydrogen separation membrane of the present invention provides superior mechanical stability as well as high hydrogen permeability at high temperatures, and can thus be valuably used for capturing carbon dioxide and separating hydrogen in pre-combustion carbon dioxide capturing.
