One step laser-induced synthesis of a bimetallic iron-cobalt sulfide for efficient solar light driven, Fenton-like and electrochemical catalysis.

ABSTRACT: Pulsed laser irradiation of an equimolar mixture of FeS₂ and CoS₂ onto a Ta substrate results in the one-step formation of bimetallic iron cobalt sulfide. The use of complementary analytical techniques, such as scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, high-resolution electron microscopy, and electron diffraction, confirmed the presence of nanocrystalline cobaltpentlandite [FeCo₈S₈] and maghemite [γ-Fe₂O₃]. The mechanism by which this occurs involves the reactive interaction of laser-ionized Fe, Co, and S species, which subsequently undergo rapid non-equilibrium cooling and deposition. The higher deposition tendency of CoS₂ along with iron ions/atoms lea
