AbstractWater splitting related to renewable energy is considered to be one of the most important strategy for hydrogen production. In this article, highly active, durable, inexpensive and magnetic FeSe2/CoFe2O4 heterojunction was fabricated via a facile two-step hydrothermal method. Subsequently, the composite was characterized by a series of physicochemical technologies, including X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microcopy (TEM), X-ray photoelectron spectra (XPS) and vibrating sample magnetometer (VSM) measurements. In order to evaluate the HER performance of the FeSe2/CoFe2O4 heterojunction, electrochemical measurements were also performed. Due to the unique band structure of FeSe2 nanorods and CoFe2O4 nanoparticles and significant coupling effect between them, the FeSe2/CoFe2O4 heterojunction exhibited excellent HER activity with a small overpotential of 231 mV at a current density of 10 mA cm(-2). Besides, it had a smaller Tafel slope of 88.76 mV.dec(-1) in acid media compared to single FeSe2 nanorods. At the same time, the heterojunction showed excellent mechanical stability with 9 h.
