    摘要:

    Pd-Ag合金膜作为分离高纯H2的金属膜目前已经商业化应用,但由于Pd-Ag合金膜的材料成本高,限制其大规模应用。 单相V基合金膜拥有比钯银合金膜更高的H渗透率、机械强度和较低的成本,且氢脆抗力较纯V得到很大提高,塑性和H渗透率也比多相V基合金膜高,因此成为替代Pd-Ag合金膜的潜在材料之一。 本文综述了氢分离单相V基合金膜的研究进展,包括V基合金膜种类及H渗透性能、微观结构对H渗透性能的影响、合金膜失效机制等,并对氢分离单相V基合金膜未来的发展趋势进行了简单的展望。

    Abstract:

    The Pd-Ag alloy membrane has been commercially used as a metal membrane for separating high-purity H2, but the material cost of the Pd-Ag alloy membrane is high, and its large-scale application is limited. The single-phase V-based alloy membranes have higher hydrogen permeability and mechanical strength and lower cost than the Pd-Ag alloy membrane, and the hydrogen embrittlement resistance is greatly improved compared with the pure V, and the plasticity and hydrogen permeability are also higher than that of multi-phase V-based alloy membranes, thus become one of the potential materials to replace the Pd-Ag alloy membrane. In this paper, the research progress of single-phase V-based alloy membranes for hydrogen separation is reviewed, including the types of single-phase V-based alloy membranes and hydrogen permeability, the influence of microstructure on hydrogen permeability, and the failure mechanism of alloy membranes, etc.. The future development trend of single-phase V-based alloy membranes for hydrogen separation is also prospected.
