“…The physiochemical properties of FeS 2 depend critically on its purity and shape; therefore, much effort has been devoted to controlling these factors. Various synthetic procedures for pyrite and applications of pyrite materials have been comprehensively reviewed in the literature [19,28,38,39]. These works show that a major challenge remains the access to single crystalline, high-purity FeS 2 materials with a precise stoichiometric ratio, as Fe 1−x S impurities are commonly observed in FeS 2 structures.…”

“…These works show that a major challenge remains the access to single crystalline, high-purity FeS 2 materials with a precise stoichiometric ratio, as Fe 1−x S impurities are commonly observed in FeS 2 structures. Structural defects coming along with these impurities (S vacancies and interstitial atoms) significantly diminish the photoelectric conversion efficiency of FeS 2 -based devices [28].…”

“…Regarding catalysis, both phase purity and morphology are of major significance for controlling and improving the performance of the catalyst material. The chemistry and syntheses of iron sulfide nanostructures [28] and thin-films [29,30], with their enormous potential for photovoltaic devices [31,32] and electrode materials [33] have been extensively reviewed in the literature. Therefore, the following article does not provide a comprehensive collection of research developments in this area, but rather highlights the latest milestones to spark the scientific communities' interest for iron sulfide electrocatalysts.…”

The chemical challenge of economically splitting water into molecular hydrogen and oxygen requires continuous development of more efficient, less-toxic, and cheaper catalyst materials. This review article highlights the potential of iron sulfide-based nanomaterials as electrocatalysts for water-splitting and predominantly as catalysts for the hydrogen evolution reaction (HER). Besides new synthetic techniques leading to phase-pure iron sulfide nano objects and thin-films, the article reviews three new material classes: (a) FeS2-TiO2 hybrid structures; (b) iron sulfide-2D carbon support composites; and (c) metal-doped (e.g., cobalt and nickel) iron sulfide materials. In recent years, immense progress has been made in the development of these materials, which exhibit enormous potential as hydrogen evolution catalysts and may represent a genuine alternative to more traditional, noble metal-based catalysts. First developments in this comparably new research area are summarized in this article and discussed together with theoretical studies on hydrogen evolution reactions involving iron sulfide electrocatalysts.

“…However, its development and application have been restricted for decades [5], owing to sulfur vacancies [6], undesired doping [7], surface conduction [8], and so on. So far, the record power conversion efficiency (PCE) of FeS 2 -based solar cells is 2.8% [9][10][11][12][13][14][15]. Therefore, extensive investigation on FeS 2 is still needed, including material synthesis, defect properties, and device physics.…”

“…Researchers have tried various methods to synthesize iron pyrite films, such as hydrothermal, hot injection, spin coating, chemical vapor deposition, physical vapor deposition, spray pyrolysis, and electrochemical deposition (ECD) [1,3,14,16,17]. Among them, ECD is the simplest and most cost-efficient method, and can produce a large-area film without a vacuum [17][18][19].…”

Iron pyrite is a cheap, stable, non-toxic, and earth-abundant material that has great potential in the field of photovoltaics. Electrochemical deposition is a low-cost method, which is also suitable for large-scale preparation of iron pyrite solar cells. In this work, we prepared iron pyrite films by electrochemical deposition with thiourea and explored the effect of sulfurization on the synthesis of high-quality iron pyrite films. Upon sulfurization, the amorphous precursor film becomes crystallized iron pyrite film. Optical and electrical characterization show that its band gap is 0.89 eV, and it is an n type semiconductor with a carrier concentration of 3.01 × 1019 cm−3. The corresponding photovoltaic device shows light response. This work suggests that sulfurization is essential in the electrochemical preparation for fabricating pure iron pyrite films, and therefore for low-cost and large-scale production of iron pyrite solar cells.

Pyrite (FeS2), as a transition metal sulfide, has a promise application in the field of secondary batteries due to its abundant reserves, high theoretical capacity, safety, and non‐toxicity. However, serious volume expansion and shuttle effect of FeS2 in liquid secondary batteries limit its further development. Solid‐state batteries offer effective solutions to these challenges. In this review, the synthesis methods of FeS2 and recent progress in FeS2‐based solid‐state lithium/sodium batteries are presented, and the effects of FeS2 size and morphology, solid electrolyte type, and battery structure design on the electrochemical performance of solid‐state batteries are discussed. By analyzing and summarizing the problems in applying FeS2 in solid‐state batteries, the remaining challenges in this field are discussed and future directions are proposed. This review aims to guide research on high‐performance solid‐state batteries based on FeS2 and promote further development of FeS2 in electrochemical energy storage.
