Unprecedented solid-transchelation reaction has been established for the synthesis of zinc pyrithione nanoparticles to control particle size within sub-micron range through direct reaction between insoluble layered zinc basic salts and aqueous sodium pyrithione solution at room temperature under ambient atmosphere. The change in crystalline phases upon reaction time clearly reveals that insoluble zinc precursors transform into zinc pyrithione nanoparticles within very short reaction time. Distinguished from usual precipitation reactions, the resulting zinc pyrithione nanoparticles exhibit a narrow size distribution. This unprecedented reaction would leads to a new route for efficient preparation of zinc pyrithione nanoparticles. And it is expected that nanosized zinc pyrithione leads to a great expansion of its application fields.
