Despite several reports on metal ferrites for water splitting studies, SnFe2O4 is a rarely explored spinel oxide. Herein, solvothermally prepared ca. 5 nm SnFe2O4 nanoparticles deposited on nickel foam (NF) behaves as a bi-functional electrocatalyst. In alkaline pH, the SnFe2O4/NF electrode exhibits oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) at moderate overpotentials and shows a fair chronoamperometric stability. Detailed study indicates that iron sites of the spinel are preferably active for the OER while the SnII sites not only enhance the electrical conductivity of the material but also favor the HER.
