| Abstract: | Flower-like MoS2 was prepared by hydrothermal synthesis.Effect of precursor concentration on the morphology of the products,and the growth mechanism were studied.Results indicate that the as-obtained samples are spherical MoS2 particles and become flower-like MoS2 with size of about 500 nm when ammonium molybdate is 10-4 mol/L,which are composed of nanopetals intercrossed with each other.Raman study of the samples indicates that the sample crystallite improves with the annealing temperature increasing. |
