Cobalt, nickel and zinc nanosized spinel-type ferrites (MFe2O4, M: Co2+ Ni2+ and Zn2+) were synthesized by the novel oil-in-water microemulsion method. These compounds have not been fully studied for H-2 production by the water-splitting reaction, especially those prepared by microemulsion. Through proper characterization, features like crystal structure, efficient visible light absorption, high-sorption capacity and adequate textural properties, were demonstrated for thermal treated Co, Ni and Zn microemulsion synthesized nanoferrites. These characteristics favored the visible light-driven H2 production (monitored by gas chromatography) of MFe2O4 nanoparticles dispersed in water (2% MeOH), under experimental conditions. Particularly, ZnFe2O4 yielded a higher amount of H-2 (354 mu molH(2)g(-1)) compared to Co (128 mu molH(2)g(-1)) and Ni (129 mu molH(2)g(-1)) ferrites in an 8 h experiment, presumably due to more favorable electronic band positions. This work represents a new contribution to the hydrogen evolution studies using ferrite nanoparticles. (C) 2018 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
