Shape-controlled synthesis of wurtzite ZnS microstructures under mild solvothermal condition.
Through a facile solvothermal route using zinc chloride and thiourea as reactants, wurtzite ZnS and its precursor ZnS . (en)0.5 (en = ethylenediamine) with various morphologies and sizes were grown, which were characterized by XRD, SEM, TEM and N2 adsorption and so on. The phase evolution, composition and morphologies of the products are highly dependent on the concentration of en. By keeping the en-water volume ratio at 1/2 to 1, the nanostripes-flower or nanorod-spheric wurtzite ZnS were easily obtained under 120 degrees C for 6-24 h, which possess relatively higher specific surface area and larger total pore volume.
