In this study, pyrite FeS2 with novel nanostructures had been obtained via an ethanolamine (ETA)–water binary system. This method provided a uniform and homogenous environment for the nucleation and growth of FeS2. When only pure water was used as the reaction solvent, marcasite FeS2 with a hollow sphere str

2018年11月10日 · Pyrite FeS 2 was synthesized through a simple, cost effective solvothermal method. NaOH was used in the synthesis, which plays a crucial role as a pH regulator. The formation of pyrite FeS 2 was confirmed through XRD, Raman Spectroscopy and FTIR. SEM results showed the formation of octahedral shaped particles with slight truncated edges.

2018年10月1日 · Pyrite iron disulfide (FeS2) is a typical representative and a popular topic among the research on metal sulfides due to its unique properties such as suitable band gap, exceptionally high optical absorption and, most importantly, the advantages of earth-abundance, nontoxicity and low cost [2].

2015年5月1日 · When only pure water was used as the reaction solvent, the marcasite FeS2 with hollow sphere structure was achieved, and then transformed into pyrite phase with rod-like structure piled up by...

2020年4月1日 · In this paper we report the synthesis of iron pyrite micro- and nano-sized crystals via simple and convenient green one-step microwave-assisted hydrothermal (M − H) process at relatively low growth temperatures, using commonly used precursors such as …

2013年1月18日 · Here, we describe a successful synthesis of single-phase pyrite nanoparticles with a diameter of 2–5 nm in polar solvent and aqueous dispersions. The particles display high uniformity and crystallographic purity.

2015年6月23日 · Pyrite (FeS2) nanocrystals with a narrow size distribution and optical absorption from 1600 to 380 nm were synthesized in a single stage by reacting ferrous chloride with elemental sulfur in oleylamine (OAm) without an additional ligand.

2025年3月3日 · MoS 2 nanosheets with 1T and 2H phases are coated on the outside of FeS 2 /C to form a porous interconnected structure that can optimize the impedance matching characteristics and strengthen the interfacial polarization loss capacity.

2017年6月8日 · The ability to synthesize pure pyrite FeS2 material is therefore critical for applications. Pure Iron pyrite nanocrystals were synthesized using hot injection by mixing sulfur with an iron precursor in the presence of an amine.

In this study, pyrite FeS2 with novel nanostructures had been obtained via an ethanolamine (ETA)–water binary system. This method provided a uniform and homogenous environment for the nucleation and growth of FeS2.
