In the present study, magnetic Cu, Co, Ni, and Zn ferrites were synthesized by co-precipitation at mild conditions. After a comprehensive characterization, the most promising materials were tested in the photo-induced hydrogen evolution reaction (photo-HER) at neutral pH, showing a significant increase in terms of current density under irradiation, and a consequent increase in H2 productivity. Specifically, CuFe2O4 exhibited the highest Faradaic Efficiency (FE of 87%) over three hours of testing (with a correspondence hydrogen evolution rate of 75 mmol h-1 g-1). These results, although preliminary, highlight how these systems can be promising photocatalysts for photo-induced HER processes.

Abstract
In the present study, magnetic Cu, Co, Ni, and Zn ferrites were synthesized by co-precipitation at mild conditions. After a comprehensive characterization, the most promising materials were tested in the photo-induced hydrogen evolution reaction (photo-HER) at neutral pH, showing a significant increase in terms of current density under irradiation, and a consequent increase in H2 productivity. Specifically, CuFe2O4 exhibited the highest Faradaic Efficiency (FE of 87%) over three hours of testing (with a correspondence hydrogen evolution rate of 75 mmol h-1 g-1). These results, although preliminary, highlight how these systems can be promising photocatalysts for photo-induced HER processes.
