Abstract

In this letter, our aim is to explore the properties of a new class of high-performance membranes for hydrogen separation applications prepared from boron-doped vanadium-aluminum alloys. In particular, we present the first hydrogen permeation characteristics of Pd-coated V _{99.8 - x}Al _xB _0.2 (x = 0, 10) alloy membranes. Membranes have been investigated in the pressure range 1.5-3.0 bar under pure hydrogen and hydrogen-carbon dioxide gas mixture at 400°C. Hydrogen flux is found on the order of 48 mL/min/cm ² for a Pd-coated V _99.8B _0.2 alloy membrane (thickness: 0.5 mm) using pure hydrogen as the feed gas.
