Highlights: • ZnS/Ni{sub 2}P composites have been firstly synthesized via a gentle hydrothermal route. • The composites have been characterized by XRD, SEM and TEM. • ZnS/Ni{sub 2}P showed enhanced photocatalytic degradation activity for pyronine B. • The reason for the enhanced photocatalytic activity has been discussed. - Abstract: ZnS/Ni{sub 2}P core/shell composites were successfully synthesized using a hydrothermal method. The composites have been characterized by XRD, SEM, TEM and the corresponding results showed that the composites were composed of the cubic ZnS microspheres, which were made up of ZnS nanoparticles, and Ni{sub 2}P nanoparticles coated on the surfaces of ZnS microspheres. Compared with ZnS microspheres, ZnS/Ni{sub 2}P core/shell composites showed enhanced photocatalytic degradation activity for pyronine B under UV irradiation. This may be related to the effective separation of photogenerated electron–hole pairs in ZnS/Ni{sub 2}P composites which can greatly reduce the chance of their recombination. Furthermore, superoxide ions and hydroxyl radical can be more easily produced through ZnS/Ni{sub 2}P composites, which is also beneficial for the degradation of pyronine B.
