Title:
HYDROGEN LEAKAGE DETECTING MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/020052
Kind Code:
A1
Abstract:
A hydrogen leakage detecting material, and a preparation method therefor and the use thereof. The hydrogen leakage detecting material comprises a color-changing substrate and an active component, wherein the color-changing substrate is hexagonal-phase tungsten trioxide having a microstructure of a nanorod bundle formed by multiple nanorods, and the active component is noble metal nanoparticles. A starting reduction temperature of the hydrogen leakage detecting material on hydrogen is less than or equal to 100°C. The hydrogen leakage detecting material has a relatively high sensitivity to hydrogen under different conditions, and has significant color change and shorter color change response time.
