Boosting NIR-driven photocatalytic water splitting by constructing 2D/3D epitaxial heterostructures

Abstract

Heterostructures, which can take advantages of materials with different properties, have attracted enormous intention in various research fields including solar cells, photocatalysts, optical electronic devices. In this work, the 2D/3D atomic epitaxial heterostructure with ultrathin BiOCl nanosheets and YF3: Yb, Tm octahedral crystals were fabricated via halogen atom exchange method in the solution phase. The epitaxial heterointerface can facilitate the energy transfer between BiOCl and YF3: Yb, Tm, and suppress the energy quenching induced by grain boundaries. By carrying out single-particle confocal characterization, the upconverted energy by YF3: Yb, Tm is quantitatively confirmed to be transferred to ultrathin BiOCl nanosheets. As a result, YF3: Yb, Tm@BiOCl displays outstanding NIR-driven water splitting and waste-water cleaning properties. This study paves the way to fabricate 2D/3D epitaxial heterostructures, which helps to broaden the application of typical 2D materials.
