Magnetize your chemistry! A facile hydrothermal synthetic route was developed for the synthesis of uniform NiS 2 hollow spheres, which could be transformed into NiSe 2 and NiTe 2 hollow spheres through a chemical conversion process (see scheme). Furthermore, NiS and NiO hollow spheres could be selectively obtained by calcination of NiS 2 hollow spheres at different temperatures.
