Hydrogen separation and purification membrane, preparation method and application thereof
The invention provides a hydrogen separation and purification membrane, a preparation method and application thereof. The hydrogen separation and purification membrane comprises a hydrogen dissociation layer, a hydrogen diffusion layer and a hydrogen recombination layer which are sequentially stacked from top to bottom, wherein the hydrogen diffusion layer is a substrate layer, the hydrogen dissociation layer and the hydrogen recombination layer are both molybdenum carbide films, and particularly molybdenum carbide in the molybdenum carbide film is of a crystalline structure. According to theinvention, the hydrogen separation and purification membrane provided by the invention improves the hydrogen permeability during hydrogen separation and purification, reduces the use cost, and provides a new choice for realizing novel, cheap, efficient and stable hydrogen separation and purification.
本发明提供了一种氢气分离提纯膜及其制备方法和应用。本发明的氢气分离提纯膜，包括自上而下依次层叠设置的氢解离层、氢扩散层和氢重组层，所述氢扩散层为基底层，所述氢解离层和氢重组层均为碳化钼薄膜；特别是，所述碳化钼薄膜中的碳化钼为晶态结构。本发明的氢气分离提纯膜提高了氢分离和提纯时的氢渗透性能并降低了使用成本，为实现新型、廉价、高效和稳定的氢气分离和提纯提供了新的选择。
