A ternary heterojunction photocatalytic material, a preparation method and application thereof

Abstract

The application provides a ternary heterojunction photocatalytic material, a preparation method and application thereof. The ternary heterojunction photocatalytic material is a bismuth oxyiodide-titanium carbide-titanium dioxide (BiOI-MXenes-TiO2) photocatalytic material derived from a single-layer titanium carbide (MXenes) carrier, and the catalytic material is successfully applied to catalytic degradation of perfluorooctanoic acid under simulated sunlight conditions for the first time. The ternary photocatalyst prepared by the application has the advantages of large specific surface area, high utilization efficiency of simulated sunlight, good promotion of separation efficiency of photo-generated electrons and holes, high photocatalytic activity, strong oxidation capacity, good stability and reusability, and the ternary heterojunction photocatalyst with the single-layer MXenes carrier is used for rapid photocatalytic degradation of perfluorooctanoic acid in water under simulated sunlight for the first time, which provides a new technical support for degradation and removal of perfluorooctanoic acid in water, and has a wide application prospect.
