Herein, we report the in situ photocatalytic deposition of cesium lead bromide (CsPbBr) perovskite quantum dots on mesoporous TiO-coated fluorine-doped tin oxide (FTO/TiO) electrodes. The mesoporous TiO layer is used as a photocatalyst to promote the following: (1) the Pb deposition from a Pb aqueous solution and (2) the in situ Pb conversion into CsPbBr perovskite in the presence of a CsBr methanolic solution without any organic capping agent. Both steps are carried out under ultraviolet light irradiation under ambient conditions without any post-treatment.

Annealing ITO at temperatures above 250 °C affects both conducting and semiconducting properties. Impressive photoelectrochemical activity was observed at this degenerate n-type semiconductor electrode, outperforming the traditional semiconductor titanium dioxide (TiO) under the same conditions.

CdS quantum dots have revealed a hydrogen generation improvement when added to TiO2 materials under visible-light irradiation. In the present paper, we investigated the performance of TiO2 nanotubes coupled with CdS quantum dots, by a molecular bifunctional linker, on photocatalytic hydrogen generation.

An informative letter with the result of the evaluation of their occupational exposure to asbestos was sent to the participating cases (and/or their family). Those whose exposure was classified as certain/probable were also informed of the legislation regarding occupational diseases.
