New publication on composite CdS/TiO2 powders

We are glad to promote a new publication prepared with the participation of our partner University of Ferrara entitled “Composite CdS/TiO₂ powders for the selective reduction of 4-nitrobenzaldehyde by visible light: relation between preparation, morphology and photocatalytic activity”.

In their work, the authors explore a series of new composite materials based on CdS/TiO₂ prepared by hydrolysis of a titania precursor in a colloidal solution of CdS nanoparticles (CdS/TiO₂-(1–4)). Exploiting the appropriate band edge position of TiO₂ and CdS, they focus on the selective visible illumination of CdS and on the subsequent injection of electrons in the conduction band of dark TiO₂. In principle, all the reductive transformations carried out by UV illumination of TiO₂ should be feasible by visible irradiation of CdS in CdS/TiO₂. The target reaction chosen is the selective reduction of p-nitrobenzaldehyde to the corresponding aniline. Textural and spectral properties of the prepared materials will be related to their photocatalytic performances. To their knowledge, the research reported is a rare example of a selective and efficient photocatalytic transformation occurring under mild conditions using visible light with a CdS-based photocatalyst with good stability
