FeS2
metalIron disulfide (pyrite, FeS₂) is a naturally occurring mineral compound that has gained attention in materials research for potential applications in energy storage and photovoltaic devices due to its semiconducting properties and earth-abundant composition. While pyrite has historically been a byproduct in metallurgical processes, contemporary interest focuses on engineered forms for next-generation batteries, solar cells, and catalytic applications where cost-effectiveness and sustainability are critical drivers. Its layered crystal structure and moderate elastic stiffness make it a subject of investigation for alternative materials to replace scarcer transition metals in electrochemical and optoelectronic devices.
