文摘

Based on the principle of thermodynamically stable nanophase, we design a strategy for fast and mass preparation of ZnS nanostructures. Under concentrated NaOH environment, where ZnS nanoarchitecture can be thermodynamically stable, ZnS nanoarchitecture was rapidly grown by using equal stoichiometric proportions of ZnO and Na₂S as reaction precursors. We demonstrate that the precursors of higher free energy can react quickly and produce the same ZnS nanoarchitecture as from slow thermodynamic transformation. The idea of thermodynamic design can be extended to a series of NaOH concentration and is insusceptible to the small changes in chemical components. We propose that the direct growth of thermodynamic stable nanomaterials has potential advantage in industrial mass production.
