“…26−28 Doping semiconducting materials with rare-earth (RE) ions holds great potential for use in a variety of new and existing industrial applications, particularly nanophotonics and photocatalysis. 29 Specifically, RE ions represent an interesting option to modify the band gap toward lower energies due to the possible transitions of f orbital electrons, which would reduce electron−hole recombination. 30 It is also well known that RE ions tend to form complexes with certain Lewis bases on the TiO 2 surface, increasing its adsorption capacity and adsorption rate simultaneously.…”

Considering CO 2 as an alternative and sustainable resource, rather than as a waste to be treated, this work proposes the combination of doped TiO 2 nanocrystals with optofluidics for the continuous photoreduction of CO 2 to alcohols under ultraviolet and visible light. This approach aims at overcoming one of the major limitations of this technology, namely, current photoreactor configurations and low activity under visible light of the up-to-date photocatalysts. Ce-doped and Cu−Ce-codoped TiO 2 nanocrystals, synthesized by a simple and green hydrothermal method with different Cu and Ce contents, are used in a planar optofluidic microreactor with an enhanced surface-area-to-volume ratio, uniform light distribution, and a larger photon receiving area. The results show promising alcohol production rates when doping the photoactive TiO 2 nanocrystals with Ce, which leads to a maximum rate of 116 μmol•g −1 •h −1 for ethanol and 106 μmol•g −1 •h −1 for methanol, exceeding most of the reported values for visiblelight-driven CO 2 photoreduction to alcohol systems. It is worth noting that the system remains pseudostable for up to 6 h of continuous operation. Altogether, this work provides novel insights into the development of innovative systems for the transformation of CO 2 to alcohols under sunlight irradiation.
