Abstract

Chemical conversion provides a versatile platform for the synthesis of advanced nanomaterials with targeted phase, composition, and architecture. Here, we report a trioctylphosphine (TOP)-driven chemical conversion route to transform lamellar Fe1−xCoxS1.2-DETA (x= 0.1, 0.3, 0.5, 0.7, DETA = diethylenetriamine) inorganic-organic hybrid solid solutions into two-dimensional (2D) single-crystal Fe1−xCoxalloy with controllable composition and dimensionality. Synergetic transformation coupled with DETA removal and sulfur extraction of lamellar Fe0.9Co0.1S1.2-DETA hybrids was examined in detail. The highest magnetization of 175 emu g−1was recorded for the prepared Fe0.7Co0.3. Our results not only provide a new lamellar inorganic-organic hybrid solid solution but also extend the chemical conversion strategy to the synthesis of previously unavailable magnetic alloy nanosheets.
