Title:
SILICON DIOXIDE-RARE EARTH COMPOSITE PHOTOCATALYTIC MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/060328
Kind Code:
A1
Abstract:
A silicon dioxide-rare earth composite photocatalytic material, a preparation method therefor, and an application thereof, utilizing a sol-gel method. A photocatalyst and a long afterglow material are simultaneously loaded onto silicon dioxide having a high specific surface area. Using high-specific-surface-area silicon dioxide having efficient adsorption and high visible light transmittance performance enhances the catalytic effect of the photocatalyst while protecting the long afterglow material which has poor water resistance, achieving a self-luminous catalysis function in low-light and dark external environments.
