Title:
COMPOSITE PALLADIUM-BASED ALLOY MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/017120
Kind Code:
A1
Abstract:
A composite palladium-based alloy material, a preparation method therefor, and a use thereof. The composite palladium-based alloy material comprises Pd and a group IB metal; and in an XRD graph of the composite palladium-based alloy material, the full width at half maximum of at least one characteristic peak for 2θ within the range of 5-90° is less than or equal to 0.1745. The present composite palladium-based alloy material has a lower activation energy for hydrogen permeation, a higher hydrogen permeation efficiency, higher stability and carbon deposition resistance, and has a longer service life as a composite membrane (especially in hydrogen production via steam reforming).
