Abstract EN
Currently, the need for more efficient materials that work in the visible light spectrum for hydrogen production has been increasing.
Under this criterion, ferrites are ideal because their energetic properties are favorable to photocatalysis as they have a low band gap (1.5 to 3 ev).
In this particular research, ferrite is presented as a hydrogen producer.
Cobalt ferrites were synthesized by chemical coprecipitation (CP) and ball milling (BM) for comparison of their performance.
The characterization of the materials was carried out with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET surface area, UV-VIS spectroscopy, and water adsorption/desorption tests.
Evaluation of the photocatalytic activity under visible light was followed by gas chromatography.
The results showed that cobalt ferrite by ball milling had a higher photocatalytic activity; this is attributed to the vacancies generated during the milling process at which the sample was exposed.
