Title:
BISMUTH TITANATE NANOSHEET/UIO-66-NH2 HETEROJUNCTION CONTAINING BISMUTH VACANCIES, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/077411
Kind Code:
A1
Abstract:
The present invention discloses a bismuth titanate nanosheet/UiO-66-NH2 heterojunction containing bismuth vacancies, a preparation method therefor and a use thereof. Titanium dioxide, bismuth oxide and inorganic salt are mixed and calcined to obtain a bismuth titanate nanosheet, and the bismuth titanate nanosheet is then immersed in an ionic cocrystal solvent to obtain the bismuth titanate nanosheet containing bismuth vacancies; and a mixture of the bismuth titanate nanosheet containing bismuth vacancies, diaminoterephthalic acid, zirconium chloride and acetic acid is subjected to hydrothermal reaction to obtain the bismuth titanate nanosheet/UiO-66-NH2 heterojunction containing bismuth vacancies. Bismuth vacancies are constructed on the bismuth titanate nanosheet by adopting a simple ionic cocrystal solvent leaching method so as to effectively increase the asymmetry of the crystal structure of the bismuth titanate nanosheet. A catalyst constructed by using the bismuth titanate nanosheet containing bismuth vacancies as a substrate and hydrothermally growing UiO-66-NH2 nanoparticles has excellent piezoelectric catalytic performance.
