Title:
TITANIUM DIOXIDE NANOBELT@MOF COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/135253
Kind Code:
A1
Abstract:
The present invention provides a titanium dioxide nanobelt@MOF composite material, a preparation method therefor, and use thereof. The preparation method comprises the following steps: preparing a titanium dioxide nanobelt; carboxylation-treating the titanium dioxide nanobelt, so as to obtain a carboxyl-modified titanium dioxide nanobelt; and mixing the carboxyl-modified titanium dioxide nanobelt, a metal salt, and an organic ligand, and then performing a heating and crystallization treatment, so as to obtain a titanium dioxide nanobelt@MOF composite material. In said method, carboxyl functional modification is performed on the surface of the TiO2 nanobelt and further an MOF material is grown in situ, allowing a simple process and low costs, achieving the preparation of a TiO2 nanobelt@MOF composite material which has a shell layer having a controllable thickness and connected by means of covalent bonds, providing a good application prospect. The titanium dioxide nanobelt@MOF composite material provided in the present invention has a porous core-shell structure having a shell layer and an inner core, the core being a titanium dioxide nanobelt, and the shell layer being an MOF layer connected to the surface of the inner core by means of covalent bonds, improving the photocatalytic performance, providing high visible light response capability.
