  • Provided a new approach for designing high-performance graded structured photocatalytic systems.

Abstract

. Combined with electron paramagnetic resonance (EPR), in situ X-ray photoelectron spectroscopy (in situ XPS) and density functional theory (DFT) calculations, the Z-scheme charge transfer mechanism is explained. This research not only provides ideas for the design of high-performance graded structured photocatalytic systems but also promotes the application of thin film catalysts in the fields of environmental remediation and optoelectronic devices.
