NiS nanobelts of hexagonal phase have been hydrothermally synthesized starting from Ni(CH{sub 3}COO){sub 2}.4H{sub 2}O and Na{sub 2}S{sub 2}O{sub 3}.5H{sub 2}O at 200 deg. C for 12 h. The as-prepared nanobelts were 50 nm thick, 70-200 nm wide and more than 10 {mu}m long. As ethylenediaminetetraacetic acid (EDTA) added, in similar condition, 2 {mu}m NiS{sub 2} microspheres of cubic phase were prepared. However, as Ni{sup 2+}/S{sub 2}O{sub 3}{sup 2-} ratio was 1:1 and the temperature was decreased to 160 deg. C, 5 {mu}m NiS{sub 2} microspheres constructed of cuboids were formed. - Graphical abstract: Hexagonal NiS nanobelts and cubic NiS{sub 2} microspheres were hydrothermally synthesized in the reaction of Ni(CH{sub 3}COO){sub 2}.4H{sub 2}O and Na{sub 2}S{sub 2}O{sub 3}.5H{sub 2}O.
