以蒽醌作催化剂，水热加氢还原从Ni（OH）2水浆制备了超细镍粉．研究了催化剂量、温度、时间、氢分压、浓度和pH等因素对还原速度和粉末粒度的影响，还原率通过X-射线衍射分析本被还原的镍来确定．用扫描电镜观察分析了粉末的粒度与形貌.研究表明，在温度高于200℃的条件下，蒽醌对Ni（OH）2浆料还原成金属镍粉是一种良好的催化剂．所得的粉末是平均粒径约为300nm的球状超细镍粉.
Using anthraquinone as catalyst, hydrothermal hydrogenation was used to prepare ultrafine nickel powder from Ni (OH) 2 water slurry. The effects of catalyst amount, temperature, time, partial pressure of hydrogen, concentration and pH on the reduction rate and particle size were investigated. The reduction rate was determined by XRD analysis of the nickel reduced. The particle size and morphology of the powder were observed by scanning electron microscopy. The results show that anthraquinone is a good catalyst for the reduction of Ni (OH) 2 slurry to metallic nickel powder at a temperature higher than 200 ℃. The resulting powder was a spherical fine nickel powder having an average particle diameter of about 300 nm.
