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

Popis výsledku v původním jazyce

The parent TiO2 and cerium doped TiO2 photocatalysts with Ce loadings 0.28-10 mol.% were prepared by the sol-gel method controlled within reverse micelles of nonionic surfactant Triton X-114. Photocatalysts were comprehensively characterized using nitrogen physisorption, XRD, XPS, contact potential difference measurements, Raman spectroscopy, and DR UV-vis spectroscopy and their performance was explored in the CO2 photocatalytic reduction for the first time. Concerning photocatalysts properties, it wasrevealed that the inhibiting effect of cerium on the TiO2 crystallites growth occurred only up to 3 mol.% of Ce when the incorporation of Ce4+ into the anatase lattice took place. This phenomenon was correlated with the expansion of anatase cell volume.At higher Ce loadings (}= 5 mol.%) the anatase lattice was saturated and the formation/separation of amorphous ceria and/or ceria (similar to 1 nm) nucleation occurred, accompanied by the increase of TiO2 anatase crystallite-size and the
