Abstract:
Magnetize your chemistry! A facile hydrothermal synthetic route was developed for the synthesis of uniform NiS2 hollow spheres, which could be transformed into NiSe2 and NiTe2 hollow spheres through a chemical conversion process. Furthermore, NiS and NiO hollow spheres could be selectively obtained by calcination of NiS2 hollow spheres at different temperatures.
