Exfoliablity, magnetism, energy storage and stability of metal thiophosphate nanosheets made in liquid medium

Abstract The family of antiferromagnetic layered metal hexathiohypo diphosphates, M 2 P S 6 represents a versatile class materials, particularly interesting for fundamental studies on magnetic properties in low dimensional structures, and yet exhibiting great potential broad variety applications including catalysis, energy storage conversion, spintronics. In this work, three representatives 2D materials (M = Fe, Ni, Mn) are exfoliated the liquid phase under inert conditions nanosheet’s studied detail different sizes all compounds. Centrifugation-based size selection is performed purpose. exfoliability structural integrity nanosheets by statistical atomic force microscopy transmission electron measurements. Further, we report thickness dependent optical spectroscopic metrics average material dimensions dispersion, as well nanomaterials’ response using combination cryo-Raman superconducting quantum interference device Finally, stability semi-quantitatively, time temperature extinction absorbance spectroscopy, enabling determination materials’ half-life, portion reacted substance macroscopic activation degradation.
