摘要: 以硫酸镍为原料,研究不同催化剂对液相氢还原法制备超细镍粉的作用效果,重点研究了催化剂用量对还原率的影响。结果表明,添加催化剂可以促进液相氢还原反应的进行,缩短反应时间,提高单位时间内氢氧化 镍浆液还原成金属镍粉的还原率;活性镍粉、PdCl2、RuCl3及蒽醌4种催化剂对比实验结果表明,使用质量浓度为 10 mg/L的PdCl2作为催化剂配料,可以使硫酸镍液相氢还原反应制备超细镍粉在最短时间内到达最高的还原率。

Abstract: With nickel sulfate as raw material,the effects of different kinds of catalyst on the preparation of ultrafine nickel powder by liquid phase hydrogen reduction process were studied.Especially,the influence of dosage of catalyst on the reduction rate was mainly investigated.Results showed that catalyst could accelerate the reaction,shorten the reaction time,and improve the rate of reducing Ni(OH)2  slurry into metal nickel per unit time.Experimental comparison results of four kinds of catalysts,namely active nickel powder,PdCl2,RuCl3,and anthraquinone,showed the hydrogen reduction reaction of nickel sulfate in liquid phase could reaching the highest reduction rate in the shortest time when PdCl2 with mass concentration of 10 mg/L was used.

Key words: catalyst, ultrafine nickel powder, hydrogen reduction in liquid phase
