Preparation, characterization and photocatalytic properties of cerium doped TiO2: On the effect of Ce loading on the photocatalytic reduction of carbon dioxide

- 0.28-10 mol.%Ce doped TiO2 was examined in CO2 photoreduction for the first time.
- Correlation between the Ce loading in TiO2 and the anatase cell volume was revealed.
- Measurements of nanoparticles work function are very valuable.
- Effect of the Ce loading on the energy of electrons and holes was evaluated.
- Energy of electrons is the crucial parameter in CO2 photocatalytic reduction.
