| 英文摘要 | Nickel power was synthesized using supercritical methanol with different nickel precursors including NiO, Ni(CH3COO)(2) and Ni(NO3)(2). The effects of temperature, pressure, reaction time, and kinds of precursors on the preparation of nickel were investigated. XRD and SEM were applied to analyze the composition and morphology of the synthesized products. Results show that the reducing capacity of supercritical methanol is enhanced obviously with the increasing of temperature and pressure, and methanol plays both roles of reaction medium and reducing agent in the reaction system. Pure ultrafine nickel could be obtained at the supercritical conditions of methanol of 250 degrees C/9 MPa using Ni(CH3COO)(2) as precursor. While much higher supercritical conditions of methanol, including temperature (280 degrees C) and pressure (14.0 MPa), are needed for Ni(NO3)(2). When using NiO as precursor, the mixture of Ni and NiO is obtained even at the more drastic supercritical condition of 300 degrees C and 20 MPa. |
