Mass Production and High Photocatalytic Activity of ZnS Nanoporous Nanoparticles

Self-assembly of hexagonal 3–5-nm ZnS nanocrystals can be used for the large-scale production of zinc sulfide nanoporous nanoparticles (NPNPs). The uniform, spherical NPNPs are monodisperse and have surface areas on the order of 156 m2 g−1. The ZnS NPNPs are more effective photocatalysts than Degussa P25 titania or ZnS nanocrystals in the photodegradation of eosin B at ambient temperature (see picture).
