Abstract

β-Ni(OH) 2 flower-like microspheres and triangular nanosheets have been hydrothermally synthesized at 180 °C in the presence of L-proline using NH 3 · H 2 O and NaOH, respectively, as the precipitant. XRD patterns show that the as-prepared β-Ni(OH) 2 products are hexagonal phase. TEM and FESEM images indicate that the flower-like microspheres with diameter of 1 ∼ 2 μm are assembled from triangular nanosheets with thickness of 15 nm and edge length of 110 nm. NiO flower-like microspheres and triangular nanosheets can be obtained by calcining the β-Ni(OH) 2 precursors at 350 °C for 2 h in air.
