Check out the latest publication from SURF on UPS to investigate Ti₂O/Cu₂O Z-scheme junctions. Beatriz de la Fuente recently published in collaboration with Jan Bomnuter, Michele del Moro, Lien Smeesters, Vanina Cristaudo, Tom Breugelmans, Vera Meynen, Pegie Cool, Annick Hubin and Tom Hauffman a full length paper on the relationship between synthesis, electronic properties and visible light absorption of TiO₂/Cu₂O Z-schemes for photocatalytic applications with a combination of surface sensitive techniques and optical absorption studies. This work is the first application of Ultraviolet Photoelectron Spectroscopy (UPS) to study the relationship between Cu₂O electrodeposition time and electronic properties of the fabricated Z-schemes. The novelty of this work concerns the several insights that can be derived from UPS on previously fabricated TiO₂/Cu₂O heterojunctions and underlines which important electronic parameters can be extracted from the spectra to help with the band diagrams tracing task. Furthermore, a laboratory scale investigation is implemented to evaluate the visible light absorption performance of Cu₂O||TiO₂ under various electrodeposition conditions.
