Insights Into the Sunlight-Driven Water Oxidation by Ce and Er-Doped ZrO ₂.

ABSTRACT: In the present work, the activity of Ce and Er-doped ZrO₂ nanopowders for sun-driven photocatalytic water oxidation has been investigated. ZrO₂ powders with tunable amounts of tetragonal, monoclinic and cubic polymorphs have been synthesized by introducing Ce and Er (from 0.5 to 10 mol % on an oxide basis) through hydrothermal method. The aim of this work is to investigate the role of rare earth (RE) ions rich of electrons (Er³⁺) and with entirely empty levels (Ce⁴⁺) in the ZrO₂ matrix for the sun-driven photocatalytic water oxidation reaction. The samples have been characterized by means of UV-Vis spectroscopy, X-Ray diffraction (XRD), N₂ adsorption, X-ray photoelectron spectrophotometry (XPS) and transmission electronic mi
